it will stay 5.2.2 since it was the version in nixpkgs when 19.03 was cut. now, for using virtualbox from unstable on your system, not sure if it's something that can be as simple as using overlays; I think there were major changes with 6.x

if you are building its configuration with something that ends up passing through nix, you could embed its store path in the configuration
<fresheyeball>
something like that should do it for you

monotux: So that gets you a python environment with everything in it that you need, I expect? now write an expression that imports that and writes a systemd unit with all of the right pieces and when you get to "run the command", you do something like "${name-you-bound-the-import-to}/bin/yourprogram ..."

the shell.nis is literally "with import <nixpkgs> {}; \n (python37.withPackages (ps: with ps; [ requests feedgen ])).env" and I just want to create something that runs a python script (the script has these dependencies) every hour or so

clever, I have a somewhat stupid question. It looks like something was pushed back in October specifically to prevent the .so files in this package from being patched using patchelf.

the nixos.wiki might have something this though

jonreeve[m]: you probably want to store the result of fetchzip in a variable in a let block `let foo = fetchzip {...}; in ..`, then create a systemd service to load the data, `script = ''do-something-with ${foo}'';`

hm. i have a problem with setting mac address of one of the interfaces to a specific value. the configuration.nix looks like this: http://dpaste.com/02CR5A6.txt , interfaces eno1 and eth1 do exist (i'm not sure why's eth1 named "eth1" and not something else conforming to "predictable" interface names but w/e); network-addresses-eth1.service (which would launch a script that would set the mac address) fails
<mog>
no im sure im just doing something wrong or the pypi is missing something
<thefloweringash>
turbo_MaCk: if you can't rebuild, something like `sudo cp --remove-destination $(readlink -f /etc/NetworkManager/NetworkManager.conf) /etc/NetworkManager/NetworkManager.conf` will make the config file editable, and then you can add the `rc-manager = resolvconf` to the `[main]` section with a regular editor

nixos, single-user: /etc/nix/nix.conf is a symlink to a read-only file in the nix store. I assume I can change its contents by setting something in /etc/nixos/configuration.nix, but I can't find any documentation on what to set...

bgamari: what I've done in the past is something like: "nix-env -qa -P --out-path --description" which generates a list of all the packages, their path in nixpkgs, their attribute name, and their description
<Notkea[m]>
I'm not sure whether I missed something… I'm simply setting some keys in my module, setting some other nested keys elsewhere, and the rest of the attribute set seems to be forgotten when serialised using toJSON
<gchristensen>
Netsu: I'll say it again, I don't know what you're doing, but I think what you're doing is not a good thing. you're hitting edge case after edge case, which should be a hint that you're using Nix for something it isn't designed.
<CMCDragonkai>
cabal2nix generates from a cabal file containing `filesystem-trees`, that dependency has a constraint on `directory >=1.1 && <1.3`, so the generated cabal.nix has `directory`, that itself cannot be fulfilled because `haskellPackages.directory` is null, but if I override it, I can state something like `{ directory = haskellPackages.directory_X_Y_Z_A; }`

clever: thanks. I had tried something similar in the past, but I retried with a more minimal example and it worked. I will progress from there thanks !

Hi, is it possible to write scripts in something other than Bash or does that invalidate all existing infrastructure wrt buildInputs etc?

what's the general approach for packages with optional unfree dependencies? do something like have them nulled out by default so they can be overridden if someone wants the unfree version? gate on `config.allowUnfree`?

yeah, in theory cmake should take something like -DPython3_ROOT_DIR but i'm not sure which magic invocation can make this work otherwise

infinisil: what if I've just got something like the linux-hardkernel-4.14.nix in nixpkgs, but I want to add `hello` to its `nativeBuildInputs`?

If I'm writing a simple custom linux kernel derivation, can I refer to the original `nativeBuildInputs` so that I can append something to the list instead of repeating all the members?
<Ankhers>
stites: Not quite. I'm thinking about whether or not I should generate one large file like that for Erlang, or if I should just have each project download directly from hex.pm. I'm hoping someone knows the tradeoffs for something like this.
<Ankhers>
Does anyone know how frequently hackage2nix gets run, and how it gets run (does someone do it manually, does Nix have some way of running these things automatically, something else)?

matt`: If they are in a seperate file you can do something like ``` let overlay1 = import /path/to/overlay.nix; in { nixpkgs.overlays = [ overlay1 ]; ... rest of config ... }

hey all. i'm just getting started using nixos and i'm having trouble figuring out how to use overlays. i've got an overlay defined in a ./overlays subdir (i've split them up by package). how do i get configuration.nix to use overlays when they're available? normally, previusly I've been using something like this: environment.systemPackages = with pkgs; [ ... ];. How do I get pkgs to refer to all nixpkgs with overlays applied? thanks!
<growpotkin>
clever: we are copying over our SQL database and it needs to be write able. I am sneaking it into the build through a derivation, and trying to copy it out and dump it into a read/write area like `/usr/mydb.sqlite3` or something

maybe it has something to do with the fact that I can't select the NixOS configuration in grub?

something like an import or similiar to use git/fetchtarball with nixos install would be neat

nix-build hangs for me when I try to build something offline. Is that normal? I think I have done offline builds before, but I'm not entirely sure

how can I do something like this: let overlay = import (./overlay.nix) {}; in import <nixpkgs> { overlays = [overlay]; } when I try to do this I get the error "error: attempt to call something which is not a function but a set". But if instead of importing overlay.nix I assign the contents to the overlay variable, then it works.

I just setup distributed builds for myself following the wiki. If a distributed build ever fails for any reason I get a "broken pipe" error. Is this the current state of error messages for distributed builds, or is there something off with my configuration?

I'm looking for something like /nix/var/nix/profiles/per-user/myuser/..../ffmpeg

Yeah, maybe NixOS does something different. Haven't done much with GUI in NixOS yet.

I just discovered something interesting. I'm trying to use a library from a really old nixpkgs commit, and it depends on the "curl" program. However this derivation is so old that the URL to download the curl source no longer exists. Does that mean it's impossible to use these derivations? You can't fake out a derivation that can no longer be built, and any change to the old curl derivation...

hi everyone, I'm trying to run a nix-shell with a the old gcc49 compiler. However when I run nix shell, even with something like "nix-shell --pure -p which" it ends up putting a bunch of things in the environment, include gcc version 7 which I don't want. I thought --pure was supposed to be a clean environment with nothing. How can I get adjust this behaviour?

Hi! I'm using gnupg agent in Nixos for handling all my gpg & ssh keys, but I have a question, is there a way to store password for keys in a keyring or something like that? do you have an alternative solution for that?
<gyroninja___>
Do I need to do something manually to fix this, or will it be resolved the next time I restart
<mla>
is there something i can throw in my configuration.nix to automatically run a command on boot, e.g. i want to change the permissions of a /sys/ filesystem device to be my user; like chown -R myuser /sys/class/backlight/intel_backlight/brightness

hm, couldn't say if it is because of u-boot failing, or something else, did you have output on screen from u-boot?
<noudle>
or something went wrong while flashing
<ris>
well that's something... i didn't know about
<monokrome>
before I installed Linux, Windows seemed to run both monitors at full resolution fine - but maybe that's just something Windows does
<hyper_ch>
I just encrypt everything - that way I won't accidentally forget to encrypt something important
<eraserhd>
If I have a PR languishing, and the maintainer of the package isn't reviewing it, can I take on maintaining the package? Is there something else I should do?
<noudle>
there is something like alsactl restore 0 failed with exit code 99, then somewhere later pluseaudio: no object for name alsa_output.pci....
<Yaniel>
probably something related to alsa, pulseaudio or tor

simpson: what path would you take if you wanted to expose Apache or Postfix or something like that to the Internet?
<Henson>
simpson: I like apparmor because it supplements Linux's access control mechanisms something more fine-grained, and Apache's mod_apparmor allows them to be applied on a virtualhost basis.
<Henson>
has anybody here used NixOS to provide secure services to the internet? I usually use apparmor, but it looks like NixOS's support for apparmor isn't quite there yet. I'm wondering if there are other mechanisms similar to AppArmor or containerization or something that provides similar security but works well in NixOS.

It'd be nice to have something like command-not-found but for man pages, to print which package to install
<clever>
mog: it might also need something like -std=c++11 to enable c++11
<ottidmes>
I do both, set nixos-config in NIX_PATH via nixPath and make /etc/nixos/configuration.nix a symlink to that file as well, unnecessary, but in the case something still assumes /etc/nixos/configuration.nix I am not in for a surprise. Have done this for years now, never had a problem
<sphalerite>
asheshambasta: yeah, you can do that. Or put a symlink to something in your home at /etc/nixos/configuration.nix
<chrisaw>
Can I do something like: pkgs.python-with-pkgs = pkgs.python-packages: with pkgs.python-packages; [ pkgs.boto ]; (for example)?

I usually like to use something like `substituteInPlace Makefile --replace /usr/local/bin ${placeholder "out"}/bin`
<zachk>
do I need to modify the #! shebang for bash scripts from /bin/bash to something else, or does that work just fine on nixos?
<Guest20>
Is it possible to have something like an "inline module" with nixos? So I can set options multiple times in the same file and they get merged by the module system.
<sgflt>
on another note: how can i disable suspend completely? i've tried powermanagement.enable = false;, however something still suspends my machine (which causes it to kernel panic and freeze)
<balder11>
Is dropbox using firefox-bin or something?
<tokudan>
how are you trying to install something?
<chrisaw>
Follow-up question - does anyone know why super.fetchPypi isn't working? Is it super.python.fetchPypi or something similar?
<tilpner>
Something is wrong about your /nix/store
<lurpahi>
Something known to be more reliable/compatible.
<infinisil>
day|flip: But you can also add something to PATH with environment.variables.PATH = [ "/foo/bar" ]
2019-06-21
<lurpahi>
… unless something like that.
<jtojnar>
lurpahi: another idea is using something different than cpio
<lurpahi>
That doesn't sound like something I have the knowledge to do.
<elvishjerricco>
Blessjah: Path literal syntax makes something that will copy the path to the store if ever interpolated into a string. So a string literal instead of a path literal won’t cause it to copy. i.e. “/foo” is different than “${/foo}”
<pbb>
is it something that can not be built from source?
<erasmas>
I'm probably missing something but I don't see how to use buildEnv or writeText for that
<elux>
like if i run some nix-shell thing, and everything in there uses the same linker or something?
<bbarker>
I just added something to my system.activationScripts which doesn't seem to be working, even after rebuilding and rebooting the system; is there a way to inspect the generated script, or force it to be run?
<pie_>
__monty__, idk off the top of my head but nix-store --query should have something
<infinisil>
Well you can just set boot.kernelPackages to something like `(import <unstable> {}).linuxPackages`
<lurpahi>
Is that something I'd have to fix in the source?
<lurpahi>
Something I'm trying to get to work seems to want to do file permission things Nix doesn't want it to do. It's using an odd format for the source archive—".cpio.7z"—and I'm getting a "cpio: …: Cannot change mode to rwxrwsrwx: Operation not permitted" from a nix-build on it.

rnhmjoj: I mostly enable Bluetooth to use headphones. Getting 200MiB additional cruft that doesn't do anything with headphones is something I wouldn't see necessary.

The bots form a queue, and the n-th bot reacts if something is left unhandled in 3n seconds
<jbaum98>
clever: so it's probably something wrong with my setup
<romildo>
If they were not optional, I would change it to something like ${gnome3.gnome-terminal}/bin/gnome-terminal. But that would mandate a dependency on gnome3.gnome-terminal.
<mpickering>
This takes <1 minute locally. Does docker make file system access much more expensive or something?
<adfaure>
__monty__: Ok, thank you. So in short, a derivation is a build process for something, could be a package, a set of packages, a file etc
<xok>
I've got something like this: 98 enableACME = ${cfg.enableSSL};
<kisik21>
Suggestions to replace gradle with something else are accepted too :3
<wucke13>
When running a build command in a nix-shell, the compiler fails with "impure path `/home/wucke13/... used in link". I guess, the nix-shell is setting something, which alters the compilers behaviour. What could it be?
<simpson>
yili: For what purpose? Usually I need something password-like, so I'd reach for something like apg.
<Shados>
clever: ...so slack has a leak? Or something that shouldn't be a leak, but effectively is because chrome doesn't reclaim that memory until something like a page change?

ashkitten: compression=lz4, xattr=sa, acltype=posixacl, optionally atime=off (or relatime=on otherwise). Build the pool, then use fio to benchmark various use-cases. Then repeat that for a whole range of ashift and recordsize values, analyse the results, and pick something that fits your workload :p. The reported physical sector size usually corresponds to the best ashift, but not always. Especially on flash devices.
<clever>
ashkitten: what i typically do, is something like 1.5gig of swap + 500mb of /boot, on one disk
