gchristensen: have you configured a Hydra job to pull from a private GitHub repo? Or just generally any GitHub repo with a git:// URL rather than https:// ?
BlessJah has joined #nixos

I haven't, but it should be workable to do by giving one of the hydra users a private SSH key
srid is now known as srid``

gchristensen: nah don't bother, I can do that. Just figured you might have done this before and had a quick answer
<dhess>
I will figure it out, just trying the lazy evaluation approach first :)
<gchristensen>
dhess: I think in HOME/.ssh/id_rsa for the hydra user
swayf has quit [Remote host closed the connection]

if you rework your partitions to fit in the SSD it should work, though don't keep both disks plugged in if using UUIDs to mount as you might mount the wrong one
<eacameron>
samueldr: Is it possible to just shrink my partition on the disk first to ensure that?

and if you're using "by-path" to identify you disks, you will need to change them for the new drive

Why, when I run this command: 'nix-shell --expr '(import <nixpkgs> {}).python.withPackages (pkgs: with pkgs; [ virtualenv ])'' do I not get python in my $PATH, but if I do 'nix-shell -p 'python.withPackages (pkgs: with pkgs; [virtualenv])'' I do? How do they differ? Is it in --expr?
<MichaelRaskin>
--expr gives you dependencies for building the package, -p gives you the package itself

Should I be able to nixos-rebuild switch from a chroot?
<clever>
ij: only "nixos-rebuild boot" and "nixos-rebuild build" would work in there
<clever>
ij: switch and test involve interacting with systemd and starting services up, which wont work under chroot
<ij>
ah!
<ij>
didn't think about it needing systemd

you also need to make sure the /boot partition is available at /boot inside the chroot

Yet I'm getting an error:

"error: file ‘nixos-unstable’ was not found in the Nix search path (add it using $NIX_PATH or -I), at /var/lib/containers/evitabumgmt/etc/nixos/configuration.nix:23:23"

Nope, nixos native :D

Can someone explain the black magic that implements this function in stdenv's setup.sh?
<ivanivan>
I'm especially confused about: exec {fd}< "$fn"
<ivanivan>
`fd` was declared (`local fd`) but never set, there's no `$` (as in `$fd`) and what do the curly braces do?
<ivanivan>

I found out why I couldn't boot. I had copied corrupted kernels/initrds and nixos-rebuild boot didn't rewrite them until I removed them.
<i-am-the-slime>
I can do latest but not 4_14
<samueldr>
hyper_ch: personally, I prefer not having major version change under my feet for the kernel
<hyper_ch>
samueldr: atomic upgrades... go back to an older generation
<i-am-the-slime>
I probably have a wrong channel for nixpkgs or something.
<hyper_ch>
so I fail to see the issue
<samueldr>
sure, but I will *anyway* need to go back to an older revision, so why *have* to fail a reboot :)

How can configure order of mounting of filesystems? It is required that zfs filesystem rpool/data/data1 is mounted first, and rpool/data/data2 only after it. And when unmounting, it should be vice versa: first rpool/data/data2 and then rpool/data/data1
<hyper_ch>
why would installation of another package update the kernel?
<hyper_ch>
Izorkin: use legacy as mountpoint and define them in your hardware-configuration.nix
<i-am-the-slime>
if you add it to system packages and linux_latest points to some new vresion now?
<i-am-the-slime>
But I thought if I said: "pkgs" it looked in the nixpks channel for the package.
<Izorkin>
hyper_ch: Can you show an example?
<samueldr>
i-am-the-slime: `pkgs` inside configuration.nix will use the channel that is used for building the system; in this case, it's the channel named `nixos` for your root user
<samueldr>
i-am-the-slime: `sudo nix-channel --list` will list the channels you added
<samueldr>
you probably will see both `nixpkgs` and `nixos` in your list (judging from your nix-info run)
detran has joined #nixos
<i-am-the-slime>
Yes
<i-am-the-slime>
I guess I want everything to be unstable, actually.
ambro718 has joined #nixos
<hyper_ch>
i-am-the-slime: then issue the command I've given above
<hyper_ch>
i-am-the-slime: and then run nixos-rebuild boot --upgrade
<hyper_ch>
(I wouldn't use switch for such a big upgrade)
<i-am-the-slime>
I will do that.
<samueldr>
you may want to remove the `nixpkgs` channel you added, and fix configuration.nix if it is used in there, otherwise you'll have a system using two revisions of the channel
<Izorkin>
hyper_ch: I also have. When you restart, errors occur - Failed unmounting /var/lib/mysql/iblogs | Failed unmounting /home/user | Failed unmounting /run/user/1000
<samueldr>
(depends on WHY nixpkgs unstable is there)
<i-am-the-slime>
Well how do I know if it's used in there?
<hyper_ch>
Izorkin: I have no idea what you're doing...
<samueldr>
i-am-the-slime: rummaging through your memory and remembering why you added it... and maybe searching for instances of `<nixpkgs` in your /etc/nixos files
<samueldr>
(depending on how your configuration.nix is written; you can import other files)
<hyper_ch>
I wonder when my ZFS PR will be merged :)
<i-am-the-slime>

<viric>
dd will not exit until the data is flushed to the target
taktoa has joined #nixos
<samueldr>
same as `sync` or `eject` would (eject will sync)
<hyper_ch>
I always issue sync
<viric>
otherwise it will exit, you may unplug the USB and it would not be written.
detran has quit [Ping timeout: 240 seconds]
<i-am-the-slime>
samueldr: Why would things break because of this channel?
<hyper_ch>
but didn't know about the dd option :)
<i-am-the-slime>
Only if it's used in configuration.nix?
<viric>
samueldr: eject a usb?
<samueldr>
viric: sudo eject /dev/sdX
<viric>
I never heard of ejecting a usb
<viric>
interesting.
<samueldr>
i-am-the-slime: no specific reasons, just be warned that you still have *that* channel that can bring other older software around
<hyper_ch>
(it will fly across the room if you eject it)
<Izorkin>
hyper_ch: I'm trying to split the data into different zfs dataset ztank/nixos/nix | ztank/nixos/root1 | ztank/nixos/tmp | ztank/nixos/var As a result, when you restart, errors occur - Failed unmounting
<samueldr>
i-am-the-slime: it depends on why it was added, but configuration.nix will use the nixos channel by default
<hyper_ch>
i-am-the-slime: you could remove it and see how things go
<hyper_ch>
Izorkin: I still have no idea what and how you did
<hyper_ch>
Izorkin: as said, use legacy as mountpoint and specify things in the hardware-configuration.nix
<i-am-the-slime>
okay I just updated to nixos-unstable and ran nixos-rebuild boot --upgrade, if it blows up, I'll just go back to the older generation

Can someone explain to me how exactly I am supposed to use overlays? Suppose I put something like this into configuration.nix: nixpkgs.overlays = [ (import ./overlay) ]; Woldn't that only take effect for the system configuration - what about if I want to install a package from an overlay with nix-env?
<clever>
ambro718: you put them into the directory this line looks at
<ambro718>
clever: but I want the overlay to be next to my system configuration, e.g. in /etc/nixos/overlay, and be effective both for nix-env and nixos-rebuild
<samueldr>

just to make sur it's not your bluetooth controller that's the problem

but the audio stuff?
<ndrei>
well, if you find out you can't connect any device...
<ndrei>
or is it just you're losing audio?
<i-am-the-slime>
I can connect them for a while.
<ndrei>
yeah, and then they disconnect, it's not just that you loose audio
<i-am-the-slime>
now I just scanned for other devices
<i-am-the-slime>
and it didn't work anymore
<i-am-the-slime>
after turning bluetooth off and on again it finds quite a few devices again
<samueldr>
i-am-the-slime: just in case, `hardware.pulseaudio.package` needs to be set to `pkgs.pulseaudioFull`, it defaults to a lighter package without bluetooth support
<i-am-the-slime>
I have that pulseaudioFull
<samueldr>
(though, you might just as well have done that already)

then good, at least it isn't *that* problem

Hi! Is anybody else unable to use `nixos-install`? For me it fails with `error: path ‘/nix/store/xryr9g56h8yjddp89d6dw12anyb4ch7c-nix-1.10’ is not valid`
<bendlas>
but I'm curious, how widespread the problem is.
<ndrei>
I call it "headset"
<ndrei>
just replace the hardcoded addresses with your own
<ndrei>
https://ptpb.pw/Nk8I and this one "speakers", for when you want to switch to speakers
detran has joined #nixos
<ndrei>
you need to have "expect" and "parallel" installed
<i-am-the-slime>
hmm
<ndrei>
you can even bind it to a key combo for extract convenience, I just type in a terminal..
<i-am-the-slime>
where do you put these scripts?
<i-am-the-slime>
~/bin ?
<ndrei>
yep
hellrazor has quit [Ping timeout: 240 seconds]
<i-am-the-slime>
so I just turned the headset off and on again
<i-am-the-slime>
it's not automatically connecting now at least
<i-am-the-slime>
let's see what happens with your script
<ndrei>
they're really a brute force (but surefire) way to switch from bluetooth to speakers, circumventing many issues I experienced with the default behaviour + bugs..
<ndrei>
yeah if you've got any issues try running the commands one by one and make sure they work properly
ma27 has joined #nixos
<i-am-the-slime>
Okay so the select part selects the headset and bluez_card.... is the card's hex name?
detran has quit [Ping timeout: 256 seconds]
<ndrei>
yep, fir the card, then the headset, and the rest is pulseaudio stuff
<ndrei>
the expect script does what you'd do in bluetoothctl
<ndrei>
and the rest what you'd do in pavucontrol.. or better by command line, it moves all running sink inputs (running audio streams) to the headset
goibhniu has joined #nixos
<ndrei>
it works great for me, I was tired of 10 settings every time I switched headset/speakers
<i-am-the-slime>
Okay, you're right, I will just try the commands step by step and figure out the right hex addresses
detran has joined #nixos
<i-am-the-slime>
Should I run this through a nix-shell? Because of the parallel and expect stuff?
<ndrei>
just install them globally, parallel is an awesome tool
<ndrei>
and expect can be handy as well
sigmundv_ has joined #nixos
<ndrei>
and really you could replace parallel with xargs -n1, it's just I love this tool :)

basically, forEach for shells, in the default behavior, takes each line from stdin and runs the command you give it with {} replaced by that line
<NixOS_GitHub>
[nixpkgs] thoughtpolice pushed 4 new commits to master: https://git.io/vNpOn
<ndrei>
so in this case, pactl lists running audio streams, then for each stream parallel runs the command to move the sink input to the headset

actually, xargs -i -n1 so you can use "{}" as replacement string
<i-am-the-slime>

I was wondering if I could make variables/constants for the adapter and the headset but it seems like they don't exist inside of the "expect" block anymore

gchristensen: I think there is a call to nix-env --set in NixOS code?
<gchristensen>
I suppose it is a simple experiment to find out, but I'm hunting for if it is updated before or after the activate script runs
<i-am-the-slime>
ndrei: The thing is I can't write a loop in bash nor fish for the life of me
<i-am-the-slime>

I have the following situation, I have an encrypted hard drive and I want to be able to unlock it in stage 1 and boot to the unlocked drive in stage 2. In this case I am using sedutil (hardware encryption) instead of LUKS. And since it is full disk encryption, I will have to use something else to unlock this. It could be another drive, USB stick, or the little unencrypted partition available on the otherwise
<ottidmes>
fully encrypted disk called the PBA. I am trying to use the latter, but the problem of having a custom stage 1 build with NixOS where I unlock the drive to use for stage 2 exists no matter where I choose to put this imag.
<ottidmes>
I thought of creating a custom iso, but the iso build its own file system to boot to in stage 2, while I want it to boot to the in stage 1 unlocked file system
<clever>
ottidmes: you can use configuration.nix to modify the scripts in stage1
mrkgnao has quit [Ping timeout: 240 seconds]

ottidmes: and if you always mount that unlock partition to /boot, nixos-rebuild can update it properly

can the bind mount of /nix/store be umounted, while running?
<clever>
viric: what do you want to do?
bluesky has quit [Read error: Connection reset by peer]
<viric>
clever: cp --reflink to another place
<ottidmes>
clever: I have a fully working initrd the way I want it too, the problem is that the PBA or an USB stick for that matter, cannot simply boot in an initrd, it needs to be a bootable image of some sorts, so how can I get this envelope
<viric>
it says it cannot cross filesystem boundaries. btrfs.

Without even looking at the device.

nixpkgs/master 5967321 Frederik Rietdijk: Merge pull request #34590 from womfoo/bump/pick-2.0.1...
<viric>
MichaelRaskin: ah may be.
<ottidmes>
clever: It is meant to be used on normal boot, so it is not that my installer is not working for me, that I have covered, but how now my system is installed can I make it unlock, when I cannot boot in the regular boot files, because they are on the encrypted drive as well.
<MichaelRaskin>
clever: I think non-recursive bind is generally safer than second-mount of the device. Just because you are telling kernel the actual truth of what you want
<viric>
MichaelRaskin: I'm back at brfs.
<viric>
MichaelRaskin: that is, btrfs.
<MichaelRaskin>
Brrrr-FS?
<viric>
:)
<viric>
moreover they introduced zstd, which I like a lot.
<clever>
ottidmes: enless your using luks support within grub, the /boot needs to be in cleartext somewhere
<MichaelRaskin>
I do use it for /nix/store, because I don't really mind losing the data there, and I like BtrFS features there
<viric>
but I think I should start using snapshots in my life.
<ottidmes>
As part of the standard there is this unencrypted PBA thing, they supply you with a existing image for BIOS and EFI, but they just allow you to unlock your drive, while I want to include things like a SSH server so I can unlock it remotely

ndrei has quit [Quit: WeeChat 2.0]
<viric>
and I don't like zfs enough (it wants ram and ignores page cache)
<ottidmes>
clever: So I basically have a little unencrypted partition I can put an image, then unlock the drive, and then the normal drive as usual appears, so I should be able to just continue booting in stage 2 then
<MichaelRaskin>
viric: clever: an artist-statement way of playing with RO bind mount of store would be to use statically linked busybox copied to /tmp in unshare-d mount namespace to unmount /nix/store and spawn whatever operation is needed
<clever>
ottidmes: i think this option allows the legacy grub stub (between sector 1 and partition 1) to ask for a password and decrypt /boot/
<viric>
I don't master the unshare thing yet.
<clever>
ottidmes: you generally put /boot on that unencrypted partition, and then it gets the kernel/initrd from that

js opening network ports?
<clever>
ottidmes: at a glance, i think thats just making a /boot containing your kernel, initrd, and bootloader, formated with ext4, and gzip'd
<viric>
My concern was the fs
<MichaelRaskin>
Some time ago I did have a small number of UIDs to separate different kinds of Gecko sessions (Google-tainted, online banking, random stuff…) Now all my FF instances have different UIDs
<clever>
ottidmes: the problem, is that nixos has to modify the bootloader config every single time you `nixos-rebuild switch`, so it has to re-generate that, and re-flash the PBA
<ottidmes>
clever: Right, but could I not kexec into the thing build by nixos?

<clever>
ottidmes: hmm, yeah, you could, and that reminds me
<clever>
ottidmes: i had an idea a few months ago, about making a kexec based bootloader, for servers
<MichaelRaskin>
Marionette is the full Firefox solution for external browser control; it includes executing scripts in the browser-chrome context, if you want to.
<clever>
ottidmes: because the grub generation list for emergency rollbacks, is 100% useless on a headless server
<ottidmes>
clever: true
<clever>
ottidmes: my idea, was to make a very thin "OS", that runs sshd, and if you dont connect within 30 seconds, it boots the default config via kexec
<clever>
ottidmes: and if you do connect, you get a boot menu (or shell) over ssh

then it kexec's your choice of OS

i'd like to suggest that pull requests aren't merged until nox-review has been successfully run. if there are some broken packages, those should be fixed before merging either by the pull requester or the package maintainer or whoever. of course, some packages may have so many packages depending on it that this might not make sense, but at least in typical cases. it feels a bit stupid to break master

<srhb>
(Just in time for 18.03 amirite)
<MichaelRaskin>
Ah, it's the same image
<ivanivan>
I see a lot of lines like "sed -i '/depmod/d' Makefile" in derivations for kernel modules. Is that the accepted approach? Does depmod make any kind of sense on NixOS anyway?
<samueldr>
the efi program is on the same partition/disk than grub
detran has joined #nixos
stephenjudkins has quit [Remote host closed the connection]
<samueldr>
I'm thinking of two things to help debug the issue: 1) search online for grub and chainloading efi programs 2) finding another efi program, in case the issue is with what I'm trying to boot
<MichaelRaskin>
Sanity check: if you make this EFI program the default (i.e. call it bootx64.efi in the FS), does it work?
<samueldr>
good idea, I'll check
<clever>
ivanivan: depmod has to be ran after nix has merged every package that provides modules
<MichaelRaskin>
As for other UEFI program: I guess you can try chainloading GRUB2…

Or where in my config might I call it at the appropriate time?
<ivanivan>
ah ok
<ivanivan>
thank you!
<clever>
ivanivan: you need to ensure the kernel module is inside pkgs.linuxPackages.foo
jensens has joined #nixos
<clever>
ivanivan: and then nixpkgs will auto-build it against the right kernel
<MichaelRaskin>
When you add the package to the list of kernel module packages, NixOS will run a global depmod
ma27 has joined #nixos

and if you do boot.extraModulePackages = [ config.boot.kernelPackages.foo ]; you will always get the module for the right kernel

ive also discovered some weird things
<clever>
grub technically has zero support for nvme drives
<clever>
all grub can do, is make use of the nvme drivers, in the board firmware
<MichaelRaskin>
I don't want to reboot now, that's for sure.
<clever>
so if your firmware cant boot nvme, grub has no way to open nvme, even if you can somehow boot the grub via other means
hiratara has quit [Ping timeout: 265 seconds]

are there any other bootloaders with similar drivers?
<MichaelRaskin>
I can check in Qemu, but I won't apply any magic to Qemu in the process.
<samueldr>
I seem to remember that there is something special to do to use qemu with OVMF in nixos, am I wrong?
<Dezgeg>
you might need to pass something like -bios ${pkgs.OVMF.fd}/FV/OVMF.fd
<MichaelRaskin>
Pay no attention to the details of @ qemu and test-build

So why don't we write metakit = metakit?

because its longer, and you have to put the name in twice

the same as any other input
<iqubic>
Cool, thank you.
<clever>
{ stdenv, metakit }:
<iqubic>
Along with all of everything else that other.nix needs.
<MichaelRaskin>
iqubic: also, for recursive attribute sets inherit will take the value form the scope, and metakit = metakit will create a self-reference.
<iqubic>
Can I then put metakit into my buildDeps?
<MichaelRaskin>
(recursive means that {version="x"; name="x-${version}";} works)
<clever>
yeah
<iqubic>
MichaelRaskin: So do I not want rec in there?

That's what clever gave me, so IDK what to do.
<MichaelRaskin>
You usually want to use rec and inherit
<iqubic>
Like clever told me to do.
detran has joined #nixos
<iqubic>
Metakit isn't in nixpkgs so I wrote a derivation for that.
<iqubic>
and I need to tell nix that other.nix depends on metakit.

So I think that will work.
