<infinisil>
Profpatsch: i mean what use would floats be if you can't do anything with them
<crucialrhyme>
i remember reading i think in the nix pills that even integer division isn't actually used anywhere in any of the nixpkgs expressions, is this still true?
<crucialrhyme>
what's the easiest way to get a nix-shell that has everything in my /etc/nixos/configuration.nix, plus a few other packages?
dtulig has joined #nixos
<infinisil>
crucialrhyme: you mean everything in environment.systemPackages?
<crucialrhyme>
infinisil: yeah
<nixy>
crucialrhyme: Wouldn't your nix-shell already have access to system packages? Or do you mean with --pure?
<crucialrhyme>
ohhhh you're right. my main use of nix shells up until now had been with an FHS compatible environment to use conda
<crucialrhyme>
but yeah i can just use normal ones
<nixy>
Yeah if you're just looking to layer packages on top of system ones you can do `nix-shell -p nmap` or something

error: need temporary directory with execute permissions! tried "/run/shm", "/dev/shm", "/tmp", "/home/avi", ".", "/home/avi"
<iqubic>
error: couldn't execute temporary file
<crucialrhyme>
none of those directories even exist on nixos, which is a huge breaking change from normal linux distros
<infinisil>
iqubic: i'd think you'd have used nix long enough by now to understand that stuff needs patching
<iqubic>
Oh. So how do I get that thing to be run?
<nixy>
Yeah, nixos departs from the FHS (filesystem hierarchy standard) pretty hard
<crucialrhyme>
well, home does
<iqubic>
infinisil: I didn't actually think that would work to be honest.
<crucialrhyme>
it's possible to create a nix-shell environment that is fhs-compatible, so has all that stuff just within the environment. i use that for Anaconda Python
<nixy>
Pretty sure something like that is used to make steam work too
<samueldr>
iqubic: is your home mounted with `noexec`?
<crucialrhyme>
there's a tutorial. depending on how complicated the installer is, it could likely be adapted for your case
<iqubic>
samueldr: I don't think so.
<iqubic>
crucialrhyme: The installed is just one *.run file that I execute.
<crucialrhyme>
yeah that's exactly the same as here
<iqubic>
So what should I do?
<samueldr>
that is, unless the installer itself checks in weird and wrong way for "execute permissions" for dirs, though, installers are expected not to run properly on nixos most of the time
<iqubic>
Oh, so it won't work? That stinks.
<iqubic>
Is there a way to force this to work?
<crucialrhyme>
that link is a good starting point
<nixy>
iqubic: You can always run whatever you need to in a virtual machine, if you don't care to learn how to get it to work with nix
LoggerZZZ has joined #nixos

you have to add the installer to the nix store

This is a prprietary PC game that's not in nixpkgs. If I really want, I can just get steam and try it that way. But I find that this game works better if I use the installer vs oing through steam.

I successfully used steam-run (without steam) to run a game in the past

maybe your installer will be happy with what steam-run gives?

didn't mean to be snarky, just admitting that I haven't used or seen stdenvNoCC before

anyway.. so maybe create a package that just uses stdenvNoCC, unpacks it, and then pass that package as an input to this one?

so with this approach i don't have to repeat all those unpacking steps

No unstable updates in over a week and now hydra is 500'ing. Anyone know what's up?
<clever>
dhess: why do you want to run cleanSource on it?
<dhess>
clever: I guess I should explain. I have written some new cleanSourceWith filters and I want to test them.
<clever>
ah
<clever>
i think it would be best to just have the input data not be in a tar
<dhess>
so I am creating a tarball with all the "bad" files, and I want to create a derivation that sources it, cleans it, then in checkPhase make sure the files don't exist.
randomstrangerb has quit [Ping timeout: 268 seconds]
<infinisil>
acowley: http://howoldis.herokuapp.com/ says nixos-unstable got updates (nixpkgs-unstable didn't though, no idea what's up)
<dhess>
clever: yeah I can make it a directory in the Git repo, but then I run into issues like many of the files that you want to filter are in the .gitignore :)
randomstrangerb has joined #nixos
<dhess>
I can make exceptions for them. But I figured that just stuffing a tarball in there would be easier.
<clever>
dhess: you may want to look at how nix's tests test filterSource, it runs nix inside nix
<dhess>
clever: I tried that but I cannot import into the store in a test.
<dhess>
well, not the way that test is set up
<dhess>
and it won't work on a Hydra either, I don't think.
<acowley>
infinisil: Yes, sorry, I meant nixpkgs-unstable. Its tests have been passing for several days now, but there's been a queue of jobs that won't finish.
<clever>
dhess: nix does it by operating on a secondary store within the tmpdir
<dhess>
also it's quite a bit of hoop-jumping. I think my idea to write derivations that use the "bad" directory/tarball as the source is quite clever actually. :)
<dhess>
clever: yes and as soon as you try to cleanSource something it starts complaining that the store is not writable, or that bash isn't in there, etc.
oida has quit [Ping timeout: 256 seconds]
<dhess>
clever: and you need a Nixpkgs to stand on, and I'm trying to do that without impurities, etc.
<dhess>
anyway I spent most of the day trying to make that approach work, and there be dragons.
<dhess>
this approach is very simple and fits nicely with Hydra. it'll be fine, I was just hoping I could import from a tarball
<dhess>
which I can, I guess... I just can't clean it
<dhess>
I guess I'll just put everyting in a local directory, refer to it directly, and make .gitignore exceptions for the crufty files.
Fare has quit [Ping timeout: 248 seconds]
ryanarte_ has joined #nixos
<dhess>
it would be cool if cleanSource could unpack a thing, though.
<clever>
dhess: cleanSource just uses filterSource behind the scenes, and filterSource is meant to filter things as they get copied from the mutable filesystem to the immutable nix store
<clever>
dhess: and most fo that filtering is to prevent the hash from changing
<dhess>
yeah that is why I'm writing new cleanSourceWith filters.
<clever>
but if the input is another derivation, you already locked the hash of things in with a fixed-output derivation, so it doesnt really work there
<jtojnar>
Why would `$ nix-instantiate -E 'args@{foo, ...}: builtins.trace args {}' --arg foo 5 --arg bar 6` not see the bar argument?
<dhess>
had all kinds of weird rebuilding things going on in my Nix-based Haskel projects
hakujin has joined #nixos
ryanartecona has quit [Ping timeout: 240 seconds]
<dhess>
now they're all fixed but all of the filters only exist in that one project. I want to separate them out into an overlay that I can import into other projects.
<dhess>
maybe upstream them when they're more mature
<dhess>
clever: ahh right that makes sense about the hash of the other derivation. So it's probably a good thing that this didn't work.

boot with zfs patch 8684 applied, load current encrypted dataset, create new encrypted dataset with new format, zfs send | receive the Nixos childset, export both, re-import old with a different name... re-import new with current name

having a backup installer in /boot would let you fix it

hyper_ch2: can I do something like "zfs set encryption=on tank/foo" to enable it on tank/foo if tank/foo already exists but is unencrypted?
<hyper_ch2>
no that won't work
<hyper_ch2>
encryption is required on dataset creation
<dhess>
ugh :(
<dhess>
that's too bad
<dhess>
do you know if there are plans to implement that?
<hyper_ch2>
dhess: you could create an encrypted dataset (I name mine "encZFS") and then just snapshot an unencrypted one and send it to that "container": zfs snapshot tank/someDS@now ; zfs send tank/someDS@now | zfs receive tank/encZFS/someDS
<dhess>
I have like... about 50T of data that I want to encrypt
<hyper_ch2>
dhess: because of inheritance the newly created DS will be encrypted
<hyper_ch2>
afterwards you could move it back though with raw sending
<hyper_ch2>
and that image... the people in #zfsonlinux said that test was poorly conducted

hi all, I'm trying to add a python package to nixpkgs. Some tests fail and it's an upstream issue. https://github.com/jeetsukumaran/DendroPy/issues/74 , what's the common practice? disable the test suite entirely or patch the source to disable the failing test?

patch source to disable failing test and make a notice in the nix expression I think

Hello, I'm working with pipenv to run flake (via tox), but I get a locale problem.

Errors, nix-info: https://paste.gnugen.ch/raw/lEq3 I can't use nix-shell, only pipenv because my workmates are not under nixos. Is there any
<Orbstheorem[m]>

Well, I'd recommend one of two options. Either try NixOS (it's nice, honest!), or you could manually populate /run/opengl-driver using symlinks to the actual driver in /usr.

There you go, then. But unless it's the exact same driver version, it won't work too well.

API mismatches always cause trouble.
ThatDocsLady has joined #nixos
<Baughn>
You get a choice. Either have a mismatch between the application and the GL library, or between the GL library and the running GL driver.
<genesis>
mismatches because not build against the kernel ?
<Baughn>
That, and what's running in the X server.
xcmw has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]
<Baughn>
I'd pick the "mismatch between application and GL library" option, because that API is actually *supposed* to be replaceable. Applications built against one driver should work fine with another, let alone minor version changes.
<Baughn>
LD_PRELOAD is usually the wrong choice. :P

Hi! I'm trying to compile some Haskell code using stack --nix, and it complains about my /run being full (I think, the actual error is "no space left on device"). Any idea?
<pmeunier>
(I'm not familiar with the Haskell infrastructure)
<Unode>
pmeunier: check available space on your local disk
<Baughn>
genesis: No, what I meant was using `LD_LIBRARY_PATH=/usr/lib glxinfo`.
<Baughn>
Or wherever libGL.so is.
<pmeunier>
and actually /run is a tmpfs, so I suspect it's rather a memory problem than a disk problem, but I was hoping there would be a workaround
acarrico has joined #nixos
<Baughn>
genesis: LD_LIBRARY_PATH doesn't override the built-in paths, so it'll still use Nix' libraries for everything else.
<genesis>
Baughn glxinfo: error while loading shared libraries: libz.so.1: cannot open shared object file: No such file or directory
<michaelpj>
pmeunier: I guess I'm not sure what your question it: it sounds like `/run` gets full while stack is running, and this causes it to fail. You could fix that by making sure you have more space available. I don't know why it uses space in `/run`, though
<Baughn>
genesis: Interesting. Hm. Well, you could use LD_PRELOAD instead.

I believe 390.x is the latest "longer term" driver series they're releasing when I looked the other day, so bumping our version to the 390.x series should be fine (which has 4.15 fixes).
<thoughtpolice>
Although I'm not sure how long we keep the older drivers around (the other series). Personally I always go with the latest, of course, because I'm dangerous

hmm, I don't know how to put it into words right, it's a bit fuzzy, but /share is often used to stuff runtime-dependent bits shared between some packages, e.g: icons, themes, sometimes scripts. When linking /share in its entirety, it becomes easy to rely on it instead of linking to the /nix/store/.../share folder of the *actual* dependency
<samueldr>
instead of software using the /nix/store/.../share folder of the dependency**
<samueldr>
that's all a guess, I have no hard proofs that's the reason /share isn't the default

how can I enable the udev.packages for a package I'm testing through nix-build?!? The package has been WIP for a month and I've upgrade since, I've tried checking checkout out my topic branch and attempting to nixos-rebuild against it with `udev.packages = [ nameofpackage ];` in my nixos-configuration but then my machine pulls in all the old builds in order to satisfy the WIP nixpkgs. I've considered just
<vidbina>
rebasing the entire WIP branch on top of my `nixos-version --revisoin` and take it from there. Is there a clever way to just set `udev.packages` in a nix-build run or must I venture down this path of pain?
xcmw has joined #nixos
<thoughtpolice>
vidbina: Maybe you could something like 'let myPackage = pkgs.callPackage /absolute/path/to/your/pkgs/default.nix { };' then use myPackage inside of udev.packages inside your configuration -- in other words, simply evaluate the expression using your NixOS's copy of nixpkgs.
<thoughtpolice>
Alternatively yes you can just rebase on top of whatever NixOS version you're using and rebuild with that.

vidbina has joined #nixos
<freeman42x>
I would like to add https://github.com/lamdu/lamdu to nixpkgs but it has dependencies of some C/++ libraries.
<freeman42x>
Is it ok if I package a C library dependency and submit it to nixpkgs? Or do I need to package everything before submitting? (I might never finish packaging all of it, but I will try)
<tobiasBora>
I'd like to know, I need to install geckodriver to make my script working. However, geckodriver is not packed in nix, so I need to do it myself. And on the website, I can find the binaries and the source code. Should I always put the source in the nix package, or can I also provide a link to the official binaries if needed ?
LoggerZZZ has quit [Remote host closed the connection]
<thoughtpolice>
tobiasBora: builds-from-source are preferred for a number of reasons (easier to overrides/configure for users, ensures the build is pure, etc) so yes, always use the source if you can. In the event you do use the source, binary packages are mostly redundant anyway (because Hydra will build them for you).
<infinisil>
tobiasBora: um, geckodriver is packaged though?
fuyuuri has quit [Ping timeout: 240 seconds]

thoughtpolice: ok thank you. But if needed I can specify an additional binary ??
<tobiasBora>
infinisil: really? I checked a few days ago, I should have miss it
<thoughtpolice>
tobiasBora: You can, but in the event of having source code there's almost never a need, and it likely would not be accepted upstream anyway (why would it, if the source packages are there?) The reason we do it for *some* packages is because they're prohibitively expensive to compile, licensing things, or stuff like that.
<thoughtpolice>
If you really wanted it, you could do it locally of course.

Plus, most of the time, building from source is easier than writing a custom expression that uses patchelf or whatever, outside of the most hostile/annoying packages. The geckodriver package itself is a good example of that as infinisil linked -- it would probably be longer and more error prone if you packaged a binary, anyway!

I installed emacs on macos with nix, but when I launch it all the keystrokes show up in the terminal instead of in emacs
<M-dpetranek>
has anybody else seen this issue?
<thoughtpolice>
elvishjerricco: That's not handled by the PR plugin ;) That's handled by the Status plugin, which does need authorization. Essentially if you read https://github.com/NixOS/hydra/blob/master/src/lib/Hydra/Plugin/GithubPulls.pm, all it does is it interrogate the GH API for the configured repo, and gets a list of PRs, and writes them as a .json file to the store
<thoughtpolice>
Then that file is passed to your declarative build as an input, so you can read the json file.
<thoughtpolice>
Then you just create jobsets declaratively like usual -- the GitHub PR .json file contains the ref you want to build, so you just include that
<thoughtpolice>
'info.head.ref'
<hyper_ch>

<elvishjerricco>
thoughtpolice: Ok... I have not yet used declarative jobsets or the github status plugin. I have a lot to learn :P
<thoughtpolice>
elvishjerricco: I've been meaning to set up a better example for my bcachefs-tools fork, but it's relatively simple. Basically: Hydra takes a .json file describing a build and reads it. This file tells hydra where to get inputs from, and what to evaluate (a file). So for example it says "clone 'foobar' from ... and evaluate the file 'hydra.nix' inside it".
<thoughtpolice>
elvishjerricco: It then tries evaluating that file (after cloning or whatever) and that evaluation should result in another .json file, and that file describes every job in a jobset.
<Mic92>
hyper_ch: not before wednesday ...
ssmike has joined #nixos
<thoughtpolice>
elvishjerricco: Here's an example of the first .json file, which tells Hydra what to evaluate. It says "evaluate default.nix from input 'src'", and 'src' is a git repository (pointing to the same gist, in fact)". Thus, hydra evaluates the default.nix, inside that gist, first off -- https://gist.github.com/thoughtpolice/b3832241c3495e0be3de0e98346cb425#file-hydra-json
<elvishjerricco>
thoughtpolice: Ok. How do you configure Hydra to look at that JSON file to begin with?
<elvishjerricco>
This looks very nice btw :)
<thoughtpolice>
elvishjerricco: Create a project on Hydra, and Edit it. Set the "declarative spec file" to hydra.json, for example, and set "Declarative input type" to "Git Checkout" and the repository containing hydra.json
<thoughtpolice>
elvishjerricco: Anyway, if you follow default.nix, it basically just writes out 'spec.json' which Hydra expects, and that json file contains information about every build. In this case I convert the attrset to JSON, but you can see the structure in 'convert'
<thoughtpolice>
elvishjerricco: Each json set produced by 'convert' describes one particular jobset. In this case, I have a jobset for each (only a single one called 'new-man' for now). Each jobset says to further evaluate release.nix inside the 'hydra' input, which again points to the same gist.
<thoughtpolice>
And that release.nix contains a jobset -- a set of builds wrapped up as a set, is all.
randomstrangerb has quit [Ping timeout: 276 seconds]
<thoughtpolice>
elvishjerricco: Note that hydra passes the inputs in the .json file, specified in the "inputs" section of the .json, to each nix expression you ask it to evaluate.
<thoughtpolice>
Thus release.nix takes both 'nixpkgs' and 'bcachefs-tools' as inputs.
randomstrangerb has joined #nixos
<thoughtpolice>
elvishjerricco: It's a bit roundabout in this case because I lock the nixpkgs revision although that's not necessary in this case, really.

<MichaelRaskin>
freeman42x: if you can test that the things you add actually work, this is a sufficient condition to submit them, in my opinion
<elvishjerricco>
thoughtpolice: One more question: How do you configure the github status stuff?
<thoughtpolice>
elvishjerricco: So if you understand all this, then the githubpulls plugin is very simple. It simply calls your evaluation to create spec.json with another argument, 'prsJSON', which is just a .json file describing all the open PRs
ssmike has quit [Ping timeout: 240 seconds]
<thoughtpolice>
And you can just create jobsets for each of these, like any branch or whatever
ryanartecona has quit [Quit: ryanartecona]
<thoughtpolice>
elvishjerricco: That one requires a modification to Hydra's server config to specify the Github authorization key, IIRC, as well as a little extra fiddling. I don't have an example on hand right now but I could probably get one working without too much issue later.
<freeman42x>

xcmw has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

elvishjerricco: for github status, when a build passes, it will find the input of the given name (cardano in the case of line 80), and lookup where on github it came from, and what rev it was in the eval
<clever>
elvishjerricco: it will then lookup the org/user owning that repo in github_authorization
<clever>
elvishjerricco: and post a static check, like travis does
<elvishjerricco>
clever: Does that work for PRs opened by random people, considering it won't have access to their fork?
<clever>
elvishjerricco: yeah
<thoughtpolice>
Yes, because GitHub implicitly mirrors all changes in forks in the master
<thoughtpolice>
So a revision in a single fork is actually available in the master copy, too.
<elvishjerricco>
ah. that explains a lot of weird behavior about GitHub forks :P

In fact, you can even use that to your advantage to pull in PRs as named refs, but anyway yeah.

To get a sha256 hash of a new source, you can use the Trust On First Use model: use probably-wrong hash (for example: 0000000000000000000000000000000000000000000000000000) then replace it with the correct hash Nix expected.
<clever>
freeman42x: simplest way is to just wait for it to fail, then it tells you the right one
<ottidmes>
infinisil: I started out with that approach as well, with my profiles (I called those machines) having modules their own modules, but most of them were shared in a shared modules folder, but now I have a main config folder I call nixcfg and each machine our machine group has a subfolder (well symlink to their repo) in it, and each those have their own config, modules, pkgs, scripts, lib, etc. making it really
<ottidmes>
consistent, while still making it easy to share via e.g. <nixcfg/subfolder/modules/...>

<clever>
freeman42x: try postUnpack = "cd src";

haha, I still think of it as disorganized as there are still some overlap between profiles and modules, and now options

Btw, if somebody wants to see some nice asciiart of systemd services dependencies, have a look at `man bootup`
<ottidmes>
infinisil: you seem to mix home stuff and system stuff in your modules folder, I am a bit confused, where is your root home-manager file, the ~/.config/nixpkgs/home.nix?
<phdoerfler>
infinisil: my curiosity is still unsatisfied as to why the systemd service guess from yours didn't work. How do I analyze that further?
<phdoerfler>
aka how to systemd if things don't do

MichaelRaskin: `quicklisp-to-nix-system-info cl-mysql` gives me an error about not being able to find libmysqlclient_r.so; does some new build input need to be added to pkgs/development/lisp-modules/shell.nix ? I would have thought mysql.connector-c should have provided that library (just guessing)
<phdoerfler>
maybe I'll remain ignorant for a little while longer :p
<phdoerfler>
until I've succeeded with the automatic reboot on security updates nix module thing
dan_b has joined #nixos

phdoerfler: oh that sounds nice

and then I shall put it on github and then there shall be no more exploitable nixos servers
<phdoerfler>
having studied it security I'm basically a bit paranoid about the whole thing and yeah that's why
<infinisil>
\o/
<infinisil>
i haven't encrypted my computer for a while now, because i redid the filesystem with zfs only and planned on using zfs encyption, but then realized it's probably a bit too early, and my backup thing wouldn't work, soo..
<phdoerfler>
infinisil: stupid question: your one-liner: That does not overwrite any other postExec scripts for that service, right?
<phdoerfler>
that's not how nix works, right?
<infinisil>
phdoerfler: it would if there was set one
<phdoerfler>
oh
<phdoerfler>
curious
<phdoerfler>
now it feels even more like a hack
<infinisil>
phdoerfler: well if you were to integrate this into the upgrade module itself it's not a hack
<ottidmes>
infinisil: Thanks, that is probably the module leotaku was talking about, do you or leotaku, perhaps know it would be possible to have both, part of your home config in the nixos config as a module, and part separate via home.nix, because see myself tweaking those home configs a lot, and I already dislike having to rebuild as often as I do right now, which would only increase if I let it handle my home config,
<ottidmes>
which is more prone to iterative experimentation
<infinisil>
phdoerfler: See nixpkgs/nixos/modules/installer/tools/auto-upgrade.nix
<MichaelRaskin>
kini: I think it needs mysql and the shipped library is just a small adaptor for weirder linker tricks
<phdoerfler>
infinisil: are you suggesting I do that and file a PR?
<phdoerfler>
or something like this
<kini>
MichaelRaskin: hmm, I tried replacing "mysql.connector-c" with "mysql" in shell.nix, but I'm seeing the same error
<phdoerfler>
infinisil: but even if it were in the upgrade module others could then overwrite that, right?
<infinisil>
ottidmes: I'm pretty sure there isn't a way to do that. The advantage of doing it all in one means that you can use all of the system config to influence your home config. This however means that you always need your system config if you want to build a new home-manager thing, so you necessarily have to build everything all the time
<leotaku>
ottidmes: Yes, I am using exactly that module
xcmw has quit [Quit: My MacBook has gone to sleep. ZZZzzz…]

phdoerfler: yeah, but that's how all services work (and is also cool thing of the module system, you can change anything you want, well mostly)
<phdoerfler>
infinisil: ok :)
<lejonet>
Is there anyway to manually trigger just a rebuild of the kernel, not the whole conf?
<infinisil>
phdoerfler: a pr that changes the auto-upgrade for a auto security reboots would make sense yeah
<MichaelRaskin>
mysql does seem to provide libmysqlclient_r.so though
<MichaelRaskin>
Maybe you need both…
<infinisil>
lejonet: nope, the conf can depend on the kernel and the kernel can depend on the conf, they are linked together and build 1 derivation
<phdoerfler>
infinisil: all it would do (for now) is to check if a new kernel version was there. That's not perfect but the "perfect" solution would be to take the rebootrequired.py script from debian and adapt it to nixos and that is way out of my comfort zone
<kini>
MichaelRaskin: I tried putting both in shell.nix and got "collision between `/nix/store/xpv4xvv9n1j8zrvy8vna5g5zs10rwlqg-mariadb-connector-c-2.3.4/bin/mariadb_config' and `/nix/store/6kl22pij3n5qppcmlg3a6m8ny19yylqj-mariadb-10.2.12/bin/mariadb_config'"
<MichaelRaskin>
Hm.
<kini>
so I guess those two derivations aren't supposed to coexist in the same environment
<phdoerfler>
that being said in the light if meltdown and whatnot I feel like "new kernel version = reboot" is not too bad

lejonet: don't include the derivation in the first rebuild?
zarel is now known as zarel_
<phdoerfler>
infinisil: haha :D

<bsima>
Is there a "nixos by example" somewhere? I'm trying to build a stack haskell project and want to see examples
<leotaku>
ottidmes: Also home-manager does not overwrite files you manually put/change in your home directory, so testing different dotfiles that way should generally be safe.
<kini>
MichaelRaskin: fwiw, mysql.connector-c also provides the required library at /nix/store/xpv4xvv9n1j8zrvy8vna5g5zs10rwlqg-mariadb-connector-c-2.3.4/lib/mysql/libmysqlclient_r.so
<kini>
so I guess the existing shell.nix isn't really incorrect, just something weird is going on
<MichaelRaskin>
Hm.
<kini>
I'm on a non-NixOS machine, would that make a difference?
<leotaku>
ottidmes: If you want to keep using an configuration you can then add it to the main configuration and rebuild. This is kind of my workflow right now.
<lejonet>
oh ofc that pulls in gcc-6.4.0 -.- damnit
<MichaelRaskin>
Shouldn't; hopefully you do have sandboxing in this case, though
<kini>
I'm not sure; how do I check?
<MichaelRaskin>
nix-info, I think
<infinisil>
kini: or just `grep sandbox /etc/nix/nix.conf`
pie_ has quit [Ping timeout: 240 seconds]

(I had to `nix-env -i nix-info` first apparently)

Maybe I should install nixos on a vm in order to work on nix stuff. That would be unfortunate though... I hoped nixos was not a strict requirement for nix hacking...

leotaku: Ah good to know that my files will be safe when rebuilding and that it does not get in the way. Yeah, I was thinking of having the same workflow! But this weekend I plan to finish my backup solution, so I will probably wait before converting too much of my config files to this approach.
<Yaniel>
went surprisingly easily except that the play button does not work
<MichaelRaskin>
And doesn't manage much outside /nix
<Yaniel>
also I have no idea how I should add its lib dir to the qt plugin path
<infinisil>
Yaniel: link to nix file?
<kini>
Oh, that's true. I guess I could do that. But there doesn't seem to be a binary installer for multi-user nix, right? Unfortunately I have some old CentOS-like system here so it's hard to compile Nix without already having a modern toolchain supplied by existing Nix
<infinisil>
It's a music player that doesn't produce any sound
<infinisil>
wait
<infinisil>
never mind
<Yaniel>
instead it produces a very specific bit pattern on the soundcard output pins?

My mind was like "it uses alsa to play stuff, totally doesn't make sound on its own", but that's stupid

actually for that matter, I don't see a complete description of how to set up multi-user nix at all. It says "$ nix-daemon" should be run by root, perhaps in a boot script, but does that mean I should call it directly by its path in the nix store? Surely that will change as nix gets upgraded? The root user doesn't have its $PATH set up to use a nix environment, so just doing `nix-daemon` as root won't work...
<MichaelRaskin>
I think you need to chown the store to root, create /etc/nix/nix.conf and launch nix-daemon
<MichaelRaskin>
Well, you can nix-build -A nix -o /somewhere/nix
<kini>
Is that what people usually do? Shouldn't the nix executables generally be running from inside /nix/ ?
