symphorien: ah k, so that file defines config.boot.kernelPatches but kernelPackages needs to use the variable kernelPatches, so the let is inheriting the later defined config.boot.kernelPatches
<symphorien>
mmmh

so if a user wants to add a kernel patch, they just pass an array of the patches they want (a number are predefined in pkgs.kernelPatches) applied to the kernel

Hi, I started to try nixos today. Up and running but I am a bit confused about some missing packages. For example I see that there should be a package 'uzbl', but 'nix-env -qa uzbl' does not return a match. I have added nixpgs-unstable as a channel.
pxc has quit [(Ping timeout: 246 seconds)]
<symphorien>
use -qaP
<juriq>

<iqubic>
tilpner: yeah, I just noticed that.
<tilpner>
juriq - If I want to see if a package exists, I use zsh tab-completion. nix-shell -p uz<TAB> completes to uzbl
<tilpner>
Or "rg uzbl" in my nixpkgs clone
<iqubic>
Is it possible to have NixOS run an arbitrary command as my WM?
<tilpner>
When?
<juriq>
tilpner: any setup needed for that, if I start zsh and type that I don't see that I can autocomplete on any letter
p4cman has quit [(Quit: Connection closed for inactivity)]
<tilpner>
juriq - I have my own zsh config, but programs.zsh.enableCompletion or programs.zsh.enableAutosuggestions might do it
<iqubic>

<tilpner>
Maybe also add an alias for nix-shell...

Unless /share/zsh/site-functions is in pathsToLink

<iqubic>
Well, I have enableCompletions set to true.
<tilpner>
/share/zsh is in pathsToLink. Hmm
<iqubic>
I thought that was the case.
<tilpner>
Still think it shouldn't work
<nh2>
what's the right way to enable core dumps on NixOS, but not using systemd's (slow) core dump feature?
<iqubic>
Either using nix-zsh-completions, or setting enableCompletion to true made my nix autocomplete stuff work.
<tilpner>
Just enableCompletion will do it, if either of that did it
<disasm>
tilpner: your correct, environment.pathsToLink = optional cfg.enableCompletion "/share/zsh"; so that's only in pathsToLink if enableCompletion is set
<juriq>
hm didn't work for me. I have set both enableCompletion, enableAutosuggestions and added nix-zsh-completions
<iqubic>
Have you shut off the terminal and turned it back on again?
<disasm>
juriq: are you using any additional custom configuration for zsh?
<disasm>
or using oh-my-zsh or prezto?
<juriq>
it was not installed so I simply installed it. Done nothing at all with it
<iqubic>
juriq: Did you edit your configuration.nix?
<iqubic>
Did you then run "nixos-rebuild switch" afterwards.
<juriq>
iqubic: yes with the three settings I mentioned above
<iqubic>
Alright, just checking.
<juriq>
then ran nixos-rebuild switch
<iqubic>
As root, right?
<tilpner>
Did you do what iqubic said about restarting your terminal?
<juriq>
yes, with sudo
<iqubic>
juriq: Have you restarted your terminal?
<juriq>
yes started zsh again
<iqubic>
How?
<juriq>
bash is default so ctrl-c and then types zsh again
<tilpner>
^C would not exit zsh
<juriq>
but tried to open a new terminal too now and same there
<juriq>
sorry ctrl-d
<iqubic>
ctrl-d won't close zsh either.
<tilpner>
iqubic - With an empty input line it will
<juriq>
I clearly get back to bash at least
<iqubic>
Oh. Yeah. I guess it will

I have however not tried anything with environment.pathsToLink mentioned above

Good morning! What does this error message mean: "warning: Nix search path entry ‘/nix/var/nix/profiles/per-user/root/channels/nixos/nixpkgs’ does not exist, ignoring" ?
<musicmatze>
I just removed an old channel on my server (17.03) and added the new one (17.09)
<srhb>
musicmatze Did you update the channel?
<srhb>
I'm not entirely sure, but looks like it could happen if it weren't downloaded yet.
<musicmatze>
as in `nixos-rebuild --upgrade` ?
<srhb>
as in nix-channel --update
<srhb>
(which is implied by nixos-rebuild --upgrade)
<musicmatze>
when doing `nixos-rebuild --upgrade build -Q` the same error message is shown...
<srhb>
musicmatze: sudo nix-channel --list ?
<musicmatze>
Ah, after running `nix-channel --update` the error message is gone.
<srhb>
Ah, good.
<musicmatze>
so `nixos-rebuild --upgrade` seems to not work as intended?
<srhb>
Not sure if it should work when it can't find nixpkgs really.
<musicmatze>
well, now it works. Lets see what I have to update in my expressions to get the upgrade going :-)
<srhb>
I agree that it's a little unintuitive.
<musicmatze>
can you explain why the docs suggest to use the -small channel for servers? I'm running the non-small on my VPS and it works beautifully...
<srhb>
The test set that the small channels run are also smaller. The tests must complete before the channels update. KDE tests are irrelevant to your server, so having them block this or that security update is probably not something you want.
<musicmatze>
there is no explanation... it just says "if server -> small channel", but not _why_
<musicmatze>
that's true
<srhb>
"hese are identical to the stable and unstable channels described above, except that they contain fewer binary packages. This means they get updated faster than the regular channels (for instance, when a critical security patch is committed to NixOS’s source tree), but may require more packages to be built from source than usual. They’re mostly intended for server environments and as such contain few GUI
<srhb>
applications."
<adisbladis>
musicmatze: Because on a server you generally require security upgrades faster
<musicmatze>
sounds right.
<musicmatze>
running two channels in parallel a good option, or should I completely switch to the small channel?
<adisbladis>
These reach unstable-small pretty fast generally but might take time to backport and the unstable channel does desktop tests which might make it lag behind
<srhb>
musicmatze: The small channel is just "ahead" of the regular ones.
<srhb>
musicmatze: I'd say it makes little sense to have both.
<eqyiel[m]>

alrighty, what are some ways of working with Jupyter in Nix? Like say I want to supply particular environments - defined with Nix expressions - to my Jupyter notebooks, are there tried and proven ways of doing that?
<srhb>
fearlessKim[m]: (I'm worried I might have pointed "too much" at the include dirs, so I'm not sure the libraries do survive"
<fearlessKim[m]>
srhb: I confirm it works. It's weird, you do "preConfigure = ''
<fearlessKim[m]>
cd lang/python" while I thought the buildPythonPackage would do it automatically. Then I had a postConfigure = ''cd lang/python''.

fearlessKim[m]: Basically I'm using the preConfigure to run the outer configure script which seems to generate the normal python stuff for a regular buildPythonPackage configurePhase

hyper_ch: nixpkgs.config.packageOverrides, not packageOverrides.

thanks you
<srhb>
hyper_ch: It's documented as a nixos option, and the actual nixpkgs config is documented in the nixpkgs manual :)
<srhb>
Both are well worth reading.
<hyper_ch>
srhb: I gave up on reading the documentations as it rarely makes any sense and has no examples and things are scattered in thousands of places

Are cross-built packages substitutable for "real" packages?

hyper_ch: Please don't, it's a little annoying to act as your documentation proxy. We can help you get familiar with where to look for which things though :)
<hyper_ch>
"We can help you get familiar with where to look for which things though" --> that's already a big problem.... you just can't find the things in the documentation
<srhb>
Right, it is difficult when you don't know which parts are nixos, which are nixpkgs and which are nix.
<srhb>
Once that starts becoming clear, it gets easier. :)

anyway, I did now add that to my configuration.nix... it didn't download/configure/install rtorrent itself...

gchristensen - Store an OCI rootfs somewhere, built with Nix. I can't store it in a tar, as it needs to be extracted before use, and where is that extraction going to live and how long...?
<toppler>
Not really a NixOS thing, but my machine has started becoming completely unresponsive under heavy disk/IO with rsnapshot. It's not something I've ever seen before.
<toppler>
Any idea what the problem could be?
<tilpner>
gchristensen - But the rootfs can contain anything, including suid executables. I don't need to be able to run them from the store, it would be remounted inside a container/VM, where it's fine to have suid
<gchristensen>
ouch

<toppler>
Moredread: Yeah, it's ssd. I'm wondering if there's a problem there. I'm also noticing that if I try to copy a large number of files to a USB stick, I get the same problem. Seems to be mention of a scheduler bug of some sort.

In your original version, that value was called pkgs. Now we're calling it oldpkgs to be extra clear. Do you think you can rewrite it using oldpkgs instead?

If you use newpkgs it's a little harder to understand. You're actually using the values FROM the new package set ot MAKE the new package set

<ixxie>
Some wireless drivers got upgraded because finally I can connect to the 5ghz network ^^
<srhb>
hyper_ch: You could do it in many ways. rtorrent-ps = import rtorrent-definition.nix {}; for instance.
<srhb>

<ixxie>
the one thing that again happened was gdm once again requires me to type in the username
<ixxie>
but I managed to fix this (imperatively) before, I just can't remember how xD
<srhb>
ixxie: is gdm.autoLogin.user broken?
<hyper_ch>
srhb: well, rtorrent-ps needs according built libtorrent file and libtorrent needs (recommended) curl, c-ares, xmlrpcs... and my original question was how I can makes sure that in a .nix file that compiles rtorrent, the according modified versions get integrated
<ixxie>
srhb: oh that's the setting?

I don't have that

<hyper_ch>
so that no matter from what computer I call it, I can just include that one .nix file into the list of system packages
<gchristensen>
it'll not be easy, bennofs
<srhb>
hyper_ch: Then you override it in the rtorrent definition instead, but that's less composable.
<srk>
any idea whats the deal here.. /nix/store/.../biun/ld: cannot find -lpthreads
<hyper_ch>
srhb: but when I already have the override stuff for kde in my configuration.nix it will complain

<bennofs>
oops, I forgot to enable SSH in my config. lol. let's do this again :D

you'd have to ensure that you get the same derivation hashes as a first step

you have all the paths as binaries for a native build
<bennofs>
i'd just need nix to produce the same hashes as-if I would build on the target
<gchristensen>
you can only produce the same hashes if you are also doing a native build
<gchristensen>
so your symlinking would have to be native to your host and pointing to a native on arm
<gchristensen>
which is ... complicated
<bennofs>
oh right. the scripts that do symlinking may depend on ARM bash etc
<gchristensen>
and also if you're doing a cross-build, I don't know if hydra does cross-builds, so you'd have to bootstrap the cross environment, so a lot of compiling
<bennofs>
gchristensen: can cross-built packages not be substituted for native packages?
<bennofs>
i thought that was the whole purpose of cross building
<gchristensen>
no they can't, because their build instructions were for a cross build not a native build :)

(Or perhaps it's just being left there because it'll cause rebuilds? I'm in no rush, just scared it'll be forgotten. :))

idk. it just makes things worse for me, b.c. usually the remotes do not even have the terminfo for the $TERM that I use locally, and that results in behaviour like backspace not working properly etc

<ixxie>
this is how I meant it
<glines>
fair enough; that's why I asked
<glines>
the tricky thing about nix-shell is it gives you an *interactive* shell, which you probably won't want for a service
<glines>
it looks like there's a --run flag for nix-shell though
jtojnar_ has quit [(Ping timeout: 255 seconds)]
<glines>
yeah, it looks like you would want the --run flag of nix-shell
<glines>
from there you can read up on how to make a systemd service for whatever distro you're using. make sure the service runs with enough permissions to call nix-shell
<ixxie>
glines: since I plan to use this to run jupyterhub, I don't mind to see stdout to make the logs visible
<glines>
??
<glines>
systemd will log anything printed to stdout, most likely
<glines>
depending on how you set it up
<ixxie>
right
seppellll has joined #nixos
<ixxie>
I have never really set up a service, so have little experience with systemd
<glines>
yeah. nix won't help you set up a service. that's the whole point of nixos. we have nixos = nix + systemd services
<glines>
basically
<ixxie>
yeah I dig

thats my understanding too, but in this case it looks like using CentOS is the way to go (this is a work machine shared with others, I don't wanna confuse them)

<MichaelRaskin>
(where nixos is the result of importing NixOS subdirectory)

you would have to read up on how to make a nixos module

honestly, making a systemd service from scratch is not very difficult

Is there any magical way to import environment into Emacs session out of a `nix-shell foo/bar.nix` invocation?
ma27 has joined #nixos
<manveru>
gleber_: you mean you call nix-shell from emacs?
<gleber_>
manveru: I have a Emacs deamon which I use to work work on multiple projects. Each project's deps are different and I try to move these deps into nix-shells. When I switch from one project to another I'd like to update Emacs' current env vars to vars imported from one of my nix-shells. Does this make sense?..
arjen-jonathan has quit [(Ping timeout: 240 seconds)]
<manveru>
that'll be tricky :)
<manveru>
i guess you could write that in elisp, something like `nix-shell foo/bar.nix --run 'env'`, parse the output, (setenv key value)
takle has joined #nixos

the tricky part is that you probably want to avoid overriding the $PATH of emacs with the nix-shell, and instead merge the two

Maybe iqubic mistook "single-user install" for any installation with only one physical user
<iqubic>
/nix is owned by root

Oh, and when you cat /etc/passwd, you'll see there are plenty of other users on your system :P

gchristensen: What do you mean by "Single-User Install"?
<iqubic>
tilpner: Yes. I do see plenty of other users.
<iqubic>
What the heck are those doing here?
<tilpner>
Privilege separation is good
<tilpner>
If you run a service as their own user instead of root or your primary user, they can do less harm
<iqubic>
But I only have one account that I log into and use on a daily basis.
<LnL>
a single user install means that /nix owned by a single (non root) user and builds also run as this user
<tilpner>
And nixbld* are the Nix build users

So I don't have a single user system. Sorry for the confusion.

err, one build in particular actually. so ideally i'd like to delete all but the current and that one
<MichaelRaskin>
nix-store --gc does not delete generations
<MichaelRaskin>
nix-collect-garbage -d does, but you can manually go to /nix/var/nix/profiles

And delete the generations you don't need

<sophiag>
it really seems to be a video driver issue rather than anything on top of x server, but no combination of fixes has solved it so far :/
<sophiag>
actually debating reinstalling from disc when i have the time...
<sophiag>
oh wow, yeah nix-store --gc freed 25gb
<MichaelRaskin>
Well, I guess going further to 17.09 gives you a new roll of the wheel w.r.t. driver combination; then you could pick the latest kernel in 17.09 just to check.
<sophiag>
yeah, i figured at this point what do i have to lose
<sophiag>
although to be clear, is just upgrading my channel to 17.09 enough?
<sphalerite>
upgrade the channel, nix-channel --update, nixos-rebuild boot
<MichaelRaskin>
Upgrading channel, rebuilding and rebooting are definitely all needed. I think nothing else.
<sphalerite>
also check the release notes
<sophiag>
ah well, the final step may not work
<sophiag>
i'm currently doing a rebuild switch, but i've purposefully commented out the changes that will crash it (i.e. the ones i was using to troubleshoot)

yeah, i know. i just got really fatigued with rebooting to troubleshoot

i do have an nvidia card, but as you can see in that issue switching to the unfree driver and latest kernel didn't solve the issue. though to be fair that was on 17.03
<disasm>
sophiag: unless you you are switching file systems reinstalling from disc is pretty pointless with nixos.
<MichaelRaskin>
Were you using nvidia card in any way on 16.03?
<MichaelRaskin>
Because I also see it's an Asus, and they use The Sensible Wiring that means that unless you do something to use Nvidia, you don't need it.
<sophiag>
oh hmm
hexamod has quit [(Quit: My MacBook has gone to sleep. ZZZzzz…)]
<sophiag>
i thought it was just an issue of the default nouveau driver
<MichaelRaskin>
If you also don't care to use nvidia card, you can block it in BIOS.
jb55 has joined #nixos
<MichaelRaskin>
We-ell. All drivers for Nvidia cards have issues.
<sophiag>
i would ideally like to use the nvidia card, but it's probably worth disabling it to see if that fixes everything
<MichaelRaskin>
Just different ones.
<sophiag>
yes, i have seen the video of linus...
<sophiag>
anyway, you're saying it's possible some package i either installed or upgraded could have started using the card and hence brought on the common issues?
<MichaelRaskin>
I have to admit that I happen to have only laptops where nouveau is okay-ish for Nvidia card
<MichaelRaskin>
No, no.
<MichaelRaskin>
The point is that xorgserver+nouveau could change their exact way of interacting with the card/
<sophiag>
ah ok
<sophiag>
hmm
<sophiag>
i should definitely just try turning it off then
<MichaelRaskin>
When you have energy to actually debug, you could try also Nvidia-only mode in BIOS
<MichaelRaskin>
It is imaginable that this _also_ works.
<sophiag>
nvidia-only?
<sophiag>
wow, damn
<MichaelRaskin>
You have two video cards wired in an interesting way.
<MichaelRaskin>
Asus generally uses sane BIOS, so it should be possible to make any of them the only one active.
<sophiag>
i will be buying a new laptop in not that long...hopefully i can avoid this nonsense. clearly the one i'm using now is meant only for windows
<rycee>
infinisil: Sorry, ran off to brush my teeth. Will go to bed now. But please have a look at my comment and see what you think :-)
<MichaelRaskin>
Nvidia-only is simpler than Intel+Nvidia (but more complex than Intel-only)
<sophiag>
well, i think i replaced uefi with grub. but i should still be able to configure the graphics easily
<MichaelRaskin>
sophiag: sorry to bring the bad news, but in general new hardware (especially from Nvidia) includes new and exciting ways to break expectations.
<sophiag>
yes, but the hardware i have now is surely particularly bad
<MichaelRaskin>
I actually prefer UEFI variant of GRUB2
<sophiag>
uefi variant?
<MichaelRaskin>
GRUB2 has UEFI support.
<MichaelRaskin>
You can install it for classical BIOS boot mode, or for UEFI mode.
<sophiag>
oh, i *think* that's just how i have it set up now
<MichaelRaskin>
Hm. What is boot.loader.grub.device though
