thomashoneyman has joined #nixos
<thomashoneyman> Hey folks! I installed NixOS last night and have been running it just fine with close to the default configuration on the command line; I haven't been able to load any display / window / desktop manager, however, and I was hoping to get some help.
<thomashoneyman> Is this a good place to ask a few questions, or is there a better way to go about this?
<thomashoneyman> I know that diagnosing issues can come down to very specific bits of configuration and it might be a bit much pouring a lot of that info into the channel.
sb0 has joined #nixos
<sb0> hi
<sb0> on NixOS, if I add a channel with name "foo", then I can install packages with:
<sb0> nix-env -f "<foo>" -iA package
<sb0> however, with the Nix package manager installed in another distribution, this doesn't work
<sb0> and I need to use, instead
<sb0> nix-env -f ~/.nix-defexpr/channels/foo/default.nix -iA package
<sb0> why?
thc202 has quit [Ping timeout: 240 seconds]
<sb0> this is also breaking "import <foo>" in other places
<elvishjerricco> sb0: Yea I think they changed the installer on other distros to not include channels in the default NIX_PATH, instead hard coding the path to the nixpkgs channel for "<nixpkgs>". I'm honestly not a fan of this change. Examine your NIX_PATH on each system and compare.
<CMCDragonkai> sb0: I don't get the channel feature, it's too inflexible. I alias my `nix-env` command to go into a nixpkgs git branch that I've cloned onto my local system
<elvishjerricco> thomashoneyman: This is the perfect place :) Here and https://discourse.nixos.org/
<sb0> elvishjerricco: why did they make that changes? it makes it very annoying to use my own channels with non-NixOS
<sb0> (they're channels with my own software, which isn't distributed with nixpkgs)
<elvishjerricco> sb0: I honestly can't tell you for sure. I think it has something to do with the fact that the new `nix` standalone command doesn't respect unlabeled directories in NIX_PATH like nix-* command do, i.e. `NIX_PATH=/somedir` as opposed to `NIX_PATH=nixpkgs=/somedir/nixpkgs`
<gchristensen> elvishjerricco: I thought we made a change to fix this :/
<elvishjerricco> Oh? I thought this was a conscious decision at one point. But it's been a while so I'm probably misremembering :P
<thomashoneyman> elvishjerrico: thanks! one sec, i'll type up a bit of background and if it seems like too much at once I can post to Discourse instead.

<gchristensen> you can add the channels as root

<gchristensen> you can file a bug report to fix this _very_ annoying bug :/
<elvishjerricco> why would it work for root?

<gchristensen> sb0: what is your NIX_PATH?

<sb0> on nixos it's /home/sb/.nix-defexpr/channels:nixpkgs=/nix/var/nix/profiles/per-user/root/channels/nixos (and some more)

<thomashoneyman> Backstory: I bought a new Dell Precision 5530 with Ubuntu 18 pre-installed. We use Nix / NixOS / Hydra at work, so I would like to dive in to NixOS for my home machine and get used to it. I produce music professionally, so I need to dual-boot Windows for some of that software to work. My goal is a functioning Windows + NixOS machine.
<thomashoneyman> Steps taken so far: I replaced the Ubuntu installation with a Windows installation. I left most of the disk unallocated. Then, I followed the instructions here to create two new partitions and install NixOS: https://qfpl.io/posts/installing-nixos/
<thomashoneyman> When I use a live installation disk for NixOS I can boot into the KDE Plasma desktop and poke around. With my NixOS installation I can boot the machine and poke around on the command line, but ONLY if I have not enabled any xserver stuff. Enabling a window manager, display manager, etc. all result in what looks like an empty terminal (black screen, blinking cursor, no contents).
<elvishjerricco> thomashoneyman: Ah, yea that's the xterm thing
<elvishjerricco> Super annoying
<thomashoneyman> Well, I'm both relieved and scared to hear you're familiar with the problem
<elvishjerricco> You have to select the right desktop environment from the login screen. There's usually a button somewhere, but I forget where on all but lightdm
<elvishjerricco> thomashoneyman: What you were *supposed* to do was inform nixos of the desired default DE in your configuration.nix, and it would have set it on first boot. But that doesn't work after the first boot anymore
drakonis has quit [Client Quit]
<gchristensen> elvishjerricco: eh? it doesn't?
<elvishjerricco> super frustrating
<thomashoneyman> I tried selecting a desktop environment with autorun=false, so that I have to explicitly start it with `systemctl start display-manager.service`
<elvishjerricco> gchristensen: At least not with lightdm. Lightdm is stateful and remembers things too well
<thomashoneyman> which is fine, because then on boot I can log in as my user or as root and do things and then i can actually start the display manager when i see fit
<thomashoneyman> that's nice, because it helps isolate that starting the display manager is what causes the blank screen
<Glenn_S> Does anyone know of a reason why systemd.services.<name>.restartTriggers wouldn't work? In particular: does it fail if the service is not currently running? I'm trying to do the following: https://pastebin.com/H3hkk21J
<elvishjerricco> gchristensen: Does it work for other login screens?
<thomashoneyman> elvishjerrico: i actually did select the desired default DE in configuration.nix on first boot, I believe

<elvishjerricco> thomashoneyman: Can you past the relevant chunk of your configuration.nix?

<gchristensen> I'm not sure, it seems to work for me?

<elvishjerricco> gchristensen: With lightdm?

<thomashoneyman> elvishjerrico: i think at one point, but not currently. i can try adding that and restarting.
<elvishjerricco> thomashoneyman: Ah yea you need that, and I think `windowManager.default` too
<thomashoneyman> the machine has NVIDIA graphics (and Intel) and I added a little to see if that was the problem -- specifically adding 'intel' and 'nvideo' as video drivers
<thomashoneyman> do you have a suggested one to try?
<thomashoneyman> i don't care which desktop / window manager etc. for the time being, just getting anything to display is a good first step :)
<elvishjerricco> thomashoneyman: Ah hm you're not using a DE... Let me check something, you might not need the desktopManager.default
<gchristensen> thomashoneyman: are you not using a DE on purpose?
<elvishjerricco> thomashoneyman: So you can just do `windowManager.default = "whatever-you-use-for-i3-probably-just-i3";`
<thomashoneyman> gchristensen: no, i'd just been unable to load the system using the default configuration.nix that's generated
<gchristensen> ok
<thomashoneyman> so i wanted to isolate the issue a bit
<thomashoneyman> i've never used a Linux machine

<jasongrossman> Gnome shell is also a fully featured desktop manager ... just not QUITE as fully featured as plasma.
<thomashoneyman> ok, i'm willing to fully replace the configuration.nix
<jasongrossman> thomashoneyman: You could also consider xmonad, since you know Haskell, but it's much much more minimalist.
<elvishjerricco> thomashoneyman: If you're already booted into the installed system, you can just do `nixos-generate-config --root /`, and then edit that file to your liking before doing `nixos-rebuild switch`
andreabedini has joined #nixos
<thomashoneyman> ok. i've regenerated the config.
<elvishjerricco> xmonad is super minimalist and extremely reliant on knowing several keybindings. I wouldn't recommend learning all those while also trying to learn to set the system up :P
<thomashoneyman> i'm going to keep it absolutely the default for now
<jasongrossman> thomashoneyman: There isn't really a default. plasma and gnome shell are both fine though.

<thomashoneyman> ok i'm rebuilding with the generated config, only changed the locale to dvorak
<elvishjerricco> thomashoneyman: I think you'll need to uncomment the generated xserver section. NixOS is not graphical by default.
<jasongrossman> thomashoneyman: When you get back to using X, you'll need xkbVariant = "dvorak";
<thomashoneyman> oh: something else i noticed -- i'm not able to just `reboot`, it hangs on `Starting mdadm-shutdown.service...`
<jasongrossman> thomashoneyman: I mean services.xserver.xkbVariant = "dvorak";
<thomashoneyman> oh, shoot, this won't work

<thomashoneyman> logical volume etc.
<elvishjerricco> thomashoneyman: Whoops :P It may have detected that and inserted the necessary parts in hardware-configuration.nix

<thomashoneyman> ah, well, not super readable
<thomashoneyman> but that's from the article i used to install this
<thomashoneyman> if I use that, then it will find the device and ask me for the password
<elvishjerricco> Huh. Well that's frustrating; nixos-generate-config really ought to catch that. What does the hardware-configuration.nix look like?
<thomashoneyman> is there a convenient way to post these files from the command line on the booted machine
<elvishjerricco> (sidenote: I personally just skip LVM. It's pointless for a single drive, and worse than ZFS for any number of drives. Not saying it's worth the trouble to undo it though)
<jasongrossman> thomashoneyman: Do you actually want your disk to be encrypted? The reason I ask is that if you've followed that guide you may have chosen encryption unnecessarily.
<jasongrossman> elvishjerricco: I believe thomashoneyman has just wiped his drive and can easily wipe it again.
<yl[m]> tobiasBora: FYI I left you comments on #56933
<{^_^}> https://github.com/NixOS/nixpkgs/pull/56933 (by tobiasBora, 1 hour ago, open): shelldap: init at 1.4.0
<elvishjerricco> I think encryption should be enabled on virtually any laptop.
<elvishjerricco> desktops it's less essential, but if you're careful it's still probably a good idea.
<elvishjerricco> on cloud hosting, it's literally pointless :P
<thomashoneyman> jasongrossman: work is adamant the disk should be encrypted
<thomashoneyman> not that it's LVM or anything
<jasongrossman> thomashoneyman: OK, cool. In the long run you might prefer ZFS ... although if your colleagues are using ext4 then maybe you'll prefer that.
<thomashoneyman> tbh i have no idea how to evaluate the differences atm
<jasongrossman> thomashoneyman: ZFS is better in every way (!) except that it's probably not be worth the bother if it's not what your colleagues are using. So forget I spoke.
<jasongrossman> - be
<thomashoneyman> to clarify a bit: this is my home laptop, but I will be writing code for work on it as well
<elvishjerricco> Yea ZFS is surprisingly interesting and amazing for something as simple as a filesystem
<elvishjerricco> but it's a bit more complicated to set up
<thomashoneyman> as long as the disk is encrypted, I don't mind wiping it entirely and starting over with ZFS
Supersonic has quit [Ping timeout: 257 seconds]
<elvishjerricco> I like it a lot for anything critical because it can tell you on its own if files are corrupted
<thomashoneyman> but being new I would need some pretty friendly resources
<jasongrossman> Well, I wouldn't say ZFS is complicated to set up. Maybe just a tiny bit more complicated than ext4. The problem with it is that it's DIFFERENT.
<elvishjerricco> I have this thing, which is even a little more complicated :P https://elvishjerricco.github.io/2018/12/06/encrypted-boot-on-zfs-with-nixos.html
<jasongrossman> elvishjerricco: I feel like we're being enablers, encouraging thomashoneyman to dive into filesystems when what he really needs is to get NixOS working. Even though nobody loves ZFS more than I do.
<thomashoneyman> haha
<thomashoneyman> i mean -- i AM here to be enabled
<jasongrossman> In THAT case, have a read about what's so great about ZFS.
<elvishjerricco> lol yea I just want ZFS to rule the world :P
<thomashoneyman> i still have my work laptop, which is a Mac running everything I need just fine

<jasongrossman> thomashoneyman: I have bad news for you then.
<thomashoneyman> no
<thomashoneyman> ok, hit me
<jasongrossman> thomashoneyman: It's almost impossible to fuck up a NixOS machine once you've got one good installation.
<jasongrossman> thomashoneyman: Sorry.
<thomashoneyman> i'm a few fuckups in so i'll be delighted to have them behind me :)
<elvishjerricco> The short list of the biggest benefits of ZFS in my opinion: The ability to rollback entire file systems; the ability to backup filesystems extremely easily; and the ability to check for corruption.
<thomashoneyman> installing windows in the first place was rough

<tobiasBora> yl[m]: you are kalbasit? Thanks for the review, I answered you.
<yl[m]> tobiasBora: yes, sorry for the confusion
<yl[m]> thx, will review
<elvishjerricco> thomashoneyman: Nah, that's common. There's very few full systems detailed in nixpkgs, so it just uses scanned info placed in hardware-configuration.nix
<thomashoneyman> it picks up two file systems, `/` which is ext4, and `/boot` which is vfat
<thomashoneyman> and a swap
<tobiasBora> yl[m]: ok thank you!
<elvishjerricco> (consider not using swap. you will regret it every time you end up needing it)
<jasongrossman> It depends how much memory you have.
<jasongrossman> And also how much memory your computer has.
<thomashoneyman> man, i specifically didn't have swap at first, but i'm tbh just bouncing around random linux articles at this point
<thomashoneyman> i have NO IDEA what i'm doing haha
<thomashoneyman> i have 32gb ram in this guy
<elvishjerricco> thomashoneyman: lol swap is just a place for the kernel to page memory out to if the system runs low on ram.
<elvishjerricco> thomashoneyman: It makes everything instantly insanely slow as soon as that starts happening
<elvishjerricco> usually unusably slow
<jasongrossman> thomashoneyman: With 32 GB of RAM you don't need swap.
<jasongrossman> thomashoneyman: I have 16 GB of RAM ... and I almost never actually use more than 8 GB.
<thomashoneyman> let's say i wanted to puzzle out some step-by-step "wipe your drive, partition it, install nixos, hey there it is"
<jasongrossman> thomashoneyman: It's different with MacOS because the system itself uses a truly immense amount of RAM.
vonfry has joined #nixos
<elvishjerricco> 8GB or more 100% does not need swap except in very specialized applications. 4GB can probably get away with it too
<thomashoneyman> elvishjerrico: i've got your article up
<thomashoneyman> i do music production professionally
<thomashoneyman> in addition to coding
<elvishjerricco> thomashoneyman: Oof, careful with that. It's not that hard, but there are several details you don't want to mess up.
<elvishjerricco> particular the keyfile you generate. Do not let that ever be visible to anyone other than root, and never copy it anywhere else

<elvishjerricco> video production too, right?
<jasongrossman> Oh, yes, OK.
<thomashoneyman> that's the only reason i'm dual booting windows
<jasongrossman> thomashoneyman: I see, good.
<elvishjerricco> (I have something even more ridiculous for dual booting windows better but I'll keep my mouth shut because that's definitely many hours worth of trouble)
<tobiasBora> Hum...
* slack1256 is curious
<elvishjerricco> *starts with*
<elvishjerricco> then you hypervise windows from the second linux system
<elvishjerricco> headlessly, so that you can VFIO the graphics card to the VM
<tobiasBora> yl[m]: before reviewing I'm thinking about something... I think I need a mkdir -p $out/bin (no -p will make it fail)
<elvishjerricco> using ZFS zvols for the VM's disk to get better performance, snapshots, etc.

<thomashoneyman> ok this boots
<thomashoneyman> elvishjerrico: what is the minimum i should enable to see if i can get a gui?
<tobiasBora> yl[m]: just, I'm not sure to understand your review: why it should not be in all packages? Is it bad to put a program in all-packages? Why does it matter if it is build in Perl?
<thomashoneyman> from the generated config
<thomashoneyman> i'm assuming i should enable `services.xserver.enable`
<yl[m]> tobiasBora: you can install it with `nix-env -f '<nixpkgs>' -iA perlPackages.Shelldap`
<tobiasBora> yl[m]: yes sure
<tobiasBora> but for example exim-tools is also in app-packages
<thomashoneyman> it also has `xserver.displayManager.sddm.enable` and `services.xserver.desktopManager.plasma5.enable` commented out
<jasongrossman> thomashoneyman: Do you have the NixOS manual, by the way?
<yl[m]> tobiasBora: you're basically creating an alias for it on the top-level, I don't think it's the right thing to do
<thomashoneyman> i do have a copy of that up
<jasongrossman> thomashoneyman: See above for the option to enable dvorak in your gui.
<tobiasBora> yl[m]: ok. I'm just trying to understand when it is the right thing to do and when it's not ;)
<thomashoneyman> got it, i'll make sure that's enabled
<yl[m]> tobiasBora: you and me both :)
<jasongrossman> thomashoneyman: Yes, enable sddm and plasma5.
<{^_^}> Channel nixos-unstable-small advanced to https://github.com/NixOS/nixpkgs/commit/d098f1311e0 (from 5 hours ago, history: https://channels.nix.gsc.io/nixos-unstable-small)
<jasongrossman> thomashoneyman: IMO, the hardest part of installing NixOS is configuring the disk. You'll be fine from now on. (See, I just jinxed it.)
<thomashoneyman> ok. i've now got the default config, except it will check for the encrypted disk, and then enabled xserver, sddm, and plasma
<thomashoneyman> but otherwise default
<jasongrossman> thomashoneyman: Nothing can go wrong.
<thomashoneyman> let's give this a try
<thomashoneyman> loading....
<thomashoneyman> NO GOOD
<thomashoneyman> rejected by the blank terminal
<thomashoneyman> oh, wait -- getting something occasionally flashing on the scree
<thomashoneyman> started load/save kill switch status...
<thomashoneyman> ok, got something new: "a start job is running for DHCP Client (22s / 1min 31s)
<thomashoneyman> appears to be frozen on that, though, not counting up
<thomashoneyman> oh! never mind, flashed again
<thomashoneyman> now i've got a nice zig-zag pattern of a few messages
<thomashoneyman> "reached target network is online"
<thomashoneyman> "reached target graphical interface"
<thomashoneyman> few others
<thomashoneyman> seems frozen again
<elvishjerricco> thomashoneyman: What does your `services.xserver` section look like?
<thomashoneyman> how could i check that+
<thomashoneyman> ?
<thomashoneyman> afaik i can't interact with this
<thomashoneyman> typing does nothing
<elvishjerricco> (also, yay my article worked)
<thomashoneyman> including say `chvt 1`
<elvishjerricco> ctrl-alt-f1 maybe?
<thomashoneyman> no luck
<thomashoneyman> side note: i can boot without the gui stuff, and i could run the gui stuff off of the live usb
<elvishjerricco> Huh, that's odd; that should have switched you to a differt vt
<thomashoneyman> nope. no key does anything to the screen
<slack1256> copy the file on /etc/nixos/configuration.nix onto http://piratepad.net and paste your link
<elvishjerricco> yea but the live CD has an excessive number of drivers installed so that it works everywhere. An install just relies on the drivers detected and placed in hardware-configuration.nix
<elvishjerricco> slack1256: They can't copy the file if they can't interact with the system :P
<elvishjerricco> so you'll probably need to reboot into the live cd and mount the disk again
<thomashoneyman> that's what i did last time
<thomashoneyman> which i'm happy to do again, but i do worry that it will lead to the same result
<elvishjerricco> thomashoneyman: You don't need to redo any of the install work
<thomashoneyman> slack1256: it's the default generated config, with nothing changed except for the xserver stuff uncommented
<thomashoneyman> and this line added:
<thomashoneyman> boot.initrd.luks.devices = [ { name = "root"; device = "/dev/nvme0n1p6"; preLVM = true; } ];

<tA> dumb question but how can i define system.packages = with pkgs; list1++list2++list3 etc etc?
<tA> i cant get the right syntax
<clever> tA: that looks like its mostly valid, what is the error code it gives?
<tA> undefined <program>
<tA> i dont really wanna put with pkgs on each individual list if i dont have to
<clever> tA: try with pkgs; ([list1] ++ [list2]); ?
<mog> i cant believe we are just 22 packages from reproducable nixos https://r13y.com/
<clever> tA: i think its parsing it as (with pkgs; [list1]) ++ [ list2]; and so the with doesnt effect the 2nd list
<tA> clever: still the same error
<clever> tA: can you pastebin the actual code you used, and the real error?
<tA> yup gimme a sec

<tA> https://pastebin.com/7dAny8nV clever, ignore the vim line numbers please
<clever> tA: for future reference, :set nonu
<clever> and :set nu, to turn them back on
<clever> tA: mpv is on line 5, and the list from 4-13 lacks a `with pkgs;`
<tA> is there anyway i can apply it after merging the list of names? i was hoping to avoid putting with pkgs on everything
<clever> you either need the with pkgs; higher up (cant say where, lines 1-3 are misisng), or put a with pkgs; on each thing
<clever> can you redo the pastebin, and include lines 1-3?
<tA> ahh i see
<tA> clever:
<clever> tA: yep, line 3, that will cover the entire file, but it might have other problems now
<clever> tA: and line 59, you are re-importing nixpkgs
<tA> yeah fixed that up now
<clever> 59 could be `with pkgs;` but since 3 now does that, 59 doesnt need a with at all
<tA> its telling me apppkgs doesnt exist, thats it evaluating those lists in alphabetical order right? do i need to put them in a let expression or something?
<clever> thats a normal set, and it cant refer to its own attrs
<clever> you likely want a let block
<clever> with pkgs; let mediapkgs = [ mpv ]; in { home.packages = mediapkgs ++ thing; }
<tA> do i need to set anything to the with pkgs; let .....? if i put it on its own line it complains about let
<clever> line endings dont really matter at all
<clever> can you pastebin what you currently have?
<tA> same link as before clever
<tA> sorry for all this, still learning
<clever> the let goes before the {
<clever> { pkgs, ... }: <value>
<clever> is a function that takes pkgs, and returns a value
<clever> let key = <value>; in <value>
<clever> is also a value
<clever> { key = <value>; } is also a value (and an attrset)
<slack1256> Is there an easy way to search the modules available to modprobe on the current kernel?
<tA> ok making lots of progress
<clever> so you basically want:
<slack1256> currently I am searching /nix/store for the current version and using `find` on that.
<clever> { pkgs, ... }: let key=value; in { key2 = value2; }
<clever> lrwxrwxrwx 13 root root 58 Dec 31 1969 /run/current-system/kernel-modules -> /nix/store/cp9ymg1diqfppadiy2395nl6s48j1pra-kernel-modules
<clever> slack1256: there is a symlink here, that points to the current modules
<tA> got it working!
<tA> thanks heaps clever, your name is apt
<clever> [clever@amd-nixos:~/Downloads]$ find -L /run/current-system/kernel-modules
<slack1256> got it!
<clever> slack1256: and this will show everything, and follow symlinks

<delan> I migrated one of my boxes from a neglected debian 8 install to nixos 18.09 the other day, but I’ve run into a very strange problem with a libvirt/KVM guest that handles my ZFS pool (freebsd 10.3 with a 9211-8i over vfio): each vdev throws well over 10 CKSUM/s when the guest scrubs the pool on nixos, damaging hundreds of files in the process, and zdb -ec crashes randomly on the exported pool, but the scrub
<delan> continues perfectly when the old debian install is restored
<delan> I realise the excessive complexity of my setup makes this a long shot, but would anyone know where I could look to narrow the problem down?

<infinisil> nh2: Add myFunction to the argument list, and use `callPackage ./myhaskellpackage.nix { inherit (pkgs) myFunction; }`

<{^_^}> [nixpkgs] @Mic92 pushed 5 commits to master: https://git.io/fhpZR
<gchristensen> ok, running the tests now Mic92
<nh2> infinisil: it feels a bit ugly though; my intent with adding it to the top-level pkgs namespace was that it is "generally available" vs having to be passed in
<gchristensen> Mic92: you aren't listed as a ZFS maintainer, would you like to be? :)
<infinisil> nh2: (I recommend overlays and `haskell.packages.ghc822.extend` btw, packageOverrides is discouraged/deprecated and `override` for haskell package sets can have odd behavior)
<infinisil> nh2: Hmm I get you..
<Mic92> gchristensen: Guess that would make sense. I need to revert the linux 5.0 regression that disabled vector instructions in zfs anyway.
<nh2> oh, I should also mention: The haskellPackages override looks like this:
<nh2> `haskellPackages = with pkgs.haskell.lib; pkgs.haskell.packages.ghc822.override { overrides = self: super: let myhaskellpackage = self.callPackage ./myhaskellpackage.nix {}; in ... }`
<nh2> is it important for callPackage's auto-passing that here things are called `self` and `super`?
<Mic92> Also I do quite a lot filesystem stuff lately
<gchristensen> what is the occasion, Mic92 ?
<srhb> nh2: Nope.
<srhb> nh2: My favourite so far for the inner ones is helf and huper :-)
<Mic92> gchristensen: regarding the vector extensions? They made a symbol private that zfs used, but they don't zfs so they don't care.

<nh2> infinisil: if I switched everything to .extend, would that change the way I could propagate the `myFunction` in wor would I still have to pass it?

<Mic92> gchristensen: I currently port a NVME driver and a rollback-protected filesystem to Intel SGX.
<gchristensen> ooooo
<nh2> infinisil: thing is, inside the `haskellPackages@{ mkDerivation, text, bytestring, ... }: mkDerivation { src = myFunction ./. }` there seems to be already a `pkgs` available even when I don't do that, but I don't know what it is. It hangs if I trace it
<infinisil> Oh hmm..
<nh2> I also wonder what would happen if somebody made a Haskell package called "pkgs"
Neo-- has joined #nixos
<infinisil> nh2: What do you mean by it hangs?
<nh2> in general the approach of passing in Haskell package names and system package names in the same attrset seems kinda questionable/confusing to me
<infinisil> No infinite recursion error even?
<nh2> infinisil: if I `src = builtins.trace pkgs ...`, the nix-build invocation hangs forever and outputs nothing
<infinisil> Weird

<Myrl-saki> infinisil: But it doesn't stop htere. Because getty@.service.d/overrides.conf still exists. Which conflicts with getty@tty1.service.d/overrides.conf.

<ldlework> doh, summon is not in nixpkgs
<srhb> noonien: My very vague feeling is that I'd prefer the builtins to be as few as possible to keep the core language really simple
Xal has joined #nixos
<srhb> noonien: So it should only implement things that are impossible in nixlang
<pie_work> this seems sketchy, i need to pass -E python27 to get this to work: pypi2nix -e unicorn -E python27
<srhb> noonien: Right now, we also have to implement things that are too _slow_ in nixlang.
<srhb> noonien: So I guess my wish is: Faster nixlang :)
<timor> noonien: I think it is good to have a clear distinction between `nix` and `nixpkgs`. The `lib` you mention comes from the latter.
<infinisil> noonien: Yeah I agree, a standard library of sorts would be nice
<noonien> for example, even easy stuff as string manipulation seems tricky in nix, for exammple https://github.com/NixOS/nixpkgs/blob/master/lib/strings.nix#L333 makes simple operations on unicode strings broken

<noonien> timor: to be honest, i'm unsure
<timor> I think that would be quite unusual
<srhb> noonien: fwiw I come from mostly Haskell, and there's a ton of top-notch libraries, and the base language is really quite small.

<noonien> srhb: i've not used any functional programming languages tbh, i dislike haskel for a number of reasons
<ldlework> do you have to get the .nix files comitted to the project?
<srhb> ldlework: iirc there's two files, one that doubles as the default.nix, one that's the deps.
<infinisil> srhb: Yeah, and I think a bunch more are also included in ghc by default, text and bytestring are part of that set
<srhb> ldlework: search the nixpkgs tree for goDeps (I think) for examples
<srhb> infinisil: True!
<ldlework> :S
<noonien> out of all the languages i've used, i came to prefer go the most. because of its stdlib, libraries tend to work together a lot better in my experience
<srhb> ldlework: Or read the nixpkgs manual go section :)

<srhb> infinisil: Thanks, I always forget that. Maybe I should just, like, hang out >_>
<srhb> It's not like I already have too much #nix-blah in my sidebar...
<noonien> and ease of code documentation, something i see nix has as well, which a LOVE! havinng to write documentation independent of code, or having to go through painful rituals and convetions makes writing documentation even more of a chore
<noonien> i'm also unsure how cross-compilation works in nix, but it would have been super great if it was built into nix, and not an artifice of nixpkgs

Seems like this may be a more haskell-specific issue though, something I need to include as an explicit dependency or something
<ddellacosta> I feel like the fact that the library it's complaining about is called "patience" is some kind of cosmic message to me
<srhb> ddellacosta: I believe so too :-)
<ddellacosta> heh
<srhb> ddellacosta: What version is it at?
<srhb> You may just need to jailbreak things.
<ddellacosta> srhb: I don't think I'm explicitly requiring that lib in my cabal file, if that's what you're asking about.
<srhb> ddellacosta: Is your package chell?
Christia7 is now known as Christia9
<srhb> ddellacosta: chell is demanding patience == 0.2.*, but your version of patience is (nix eval nixpkgs.haskellPackages.patience.version)
<srhb> ddellacosta: Which, if you're on 18.09, is 0.1.1
<ddellacosta> oh no, it's my web site, basically a hackyl install
<srhb> ddellacosta: Somehow you're (possibly transitively) depending on chell, which depends on patience in that version.

acarrico has joined #nixos
<MichaelRaskin> (because rebuilding it takes time)
<MichaelRaskin> Well, worst case is probably a glibc bug only triggered by Chromium
<sheyll> I am having trouble groking the Chapter 3.3 in the nixpkgs manual "Specifying dependencies"; I find it very hard to follow, also there seem to be gramatical errors; I wonder what the problem is that they solve, and after spending hours trying to understand this, I wouldn't mind contributing to the documentation, but I still don't know if I have understood the chapter
<{^_^}> [nixpkgs] @bachp opened pull request #56992 → unifiStable: 5.10.17 -> 5.10.19 → https://git.io/fhpEm
<infinisil> Fare: If there's a patch, it can get applied and merged rather quickly (if somebody does it that is). Then it gets also backported to stable.
<symphorien> sheyll: the gist is: buildInputs are for .so and code which goes in the build product, and nativeBuildInputs are for tools used by the build system but which are not supposed to go in the build product, for example cmake, pkgconfig etc.
<symphorien> other types of dependencies are for tricky cross compilation cases
<sheyll> first of all it says "platforms imply whether or not the dependency is needed at run-time or build-time" but the footnote 1 says: " The build platform is ignored..."
<elvishjerricco> sheyll: It's a complicated system trying to cover all the corner cases of the target/host/build triad in cross compiling. Personally I find it vastly over engineered. buildInputs and nativeBuildInputs is a good distinction but the others are.... overdone IMO
jasongrossman has quit [Quit: ERC (IRC client for Emacs 26.1)]

<sheyll> I just did 'readlink /run/current-system' and got '/nix/store/...-nixos-system-wega-18.09.2266.aabc61049c0' - I did a 'nix-store -qR' on this path and got a list that contains a lot of stuff. I this the 'whole' system, that I could copy to another system, set a few symlinks and boot into?
<sheyll> in order to clone the machine?

<jasongrossman> sheyll: I don't know, but the standard way would be to copy configuration.nix across and then regenerate the store. That way you can be sure you've got a consistent system.
<adamt> sheyll: Yeah, it should be. But you don't want to handle links manually, there's a store path that contains a binary that activates it as default

<elvishjerricco> jasongrossman: I would not say that is the standard way

<adamt> jasongrossman: We build our hosts locally, push them, and run the activation script, so that nothing is built remote
<elvishjerricco> I find it much more common (and much better) to build the system on a different system and simply `nix copy` the path to the target machine
<elvishjerricco> ^ what adamt said
<elvishjerricco> target machines (at least in my work) are generally quite weak in CPU performance, so they're no good for building on. Much easier to use Nix's excellent closure concept to just copy from a beefier build machine
<jasongrossman> I see.
<elvishjerricco> sheyll: NixOps is a tool for automating all this, as well as cloud resource provisioning. You give it a nix expression, it figures out what hardware to provision on the cloud provider, it builds the system locally, it copies it to the server, and it activates it

<adamt> sheyll: If you want to do the copying manually, here's how you can activate the new system: https://github.com/DBCDK/morph/blob/master/ssh/ssh.go#L200

<averell> someone could merge the meld commit from https://github.com/NixOS/nixpkgs/pull/56705 the conflict there is with the redundant other commit.

<sheyll> thanks adamt

<adamt> Notice how there's two binaries being called. the nix-env one is needed to persist the configuration change (generate a new generation and set it as default). `configuration` here is just a store path, I think.
<justanotheruser> not sure this is a nixos issue, however thought I might ask here: I'm trying to get cron to work. /etc/crontab looks like this https://paste.debian.net/plain/1071984 and journalctl indicates that the cron job is being run https://paste.debian.net/plain/1071983 however the file ~/cron.log isn't being written to. How can I resolve this?

<azazel> I have a problem that when my server comes up firewall fails to start because a firewall piece fails to resolve an IPv6 fqdn but then via ssh doing a "systemctl restart firewall" completes without issues.... what can it be
<azazel> justanotheruser: you really need cron when you have systemd?
<justanotheruser> azazel: I didn't realize I could replace cron functionality with systemd. Let me look into that

<azazel> just declare a timer and and an "oneshot" service with the same name
<jtojnar> ,locate cryptui-0.0
<{^_^}> Couldn't find in any packages
<justanotheruser> azazel: what is the cli equivalent to this page?
<justanotheruser> (unrelated, but I didn't realize this page existed)
<justanotheruser> good example, let me try that out
stepcut has quit [Remote host closed the connection]
<azazel> justanotheruser: what page?
<azazel> justanotheruser: it's just a searchable doc of all the configuration options, the same you can access using "man configuration.nix"
