Re: [Nix-dev] [Help] Accidentally removed configuration.nix
No I don't have `system.copySystemConfiguration=true` set :-( Luckily I documented my recent efforts in some gists. I managed to install NixOS on ZFS here: https://gist.github.com/awesomefireduck/c763e168a62a0ef559a1fb9473261459 And my (yet untested) attempt at PCI passthrough here: https://gist.github.com/awesomefireduck/1be07805081a4d7a51c527e452b87b26 There is still some missing, but nothing I can't handle, I guess. This is a great time to enable my ZFS snapshots... :-/ Does anyone know why `system.copySystemConfiguration` is set to false by default? It seems like it would be better to default this to true, right? Or at least have this listed in the generated config? (`nixos-generate-config`) Anyway, I'll be okay, thanks folks!!

[Nix-dev] Help wanted with Nixos on ZFS in an encrypted LUKS volume
Hi fellow Nix enthusiasts, I'm trying to install Nixos on a ZFS root filesystem which in turn resides in an encrypted volume (using LUKS). I already succeeded in a minimal ZFS install on an unencrypted partition, and I also succeeded in installing in an encrypted LUKS volume with ext4 as root fs. But with the combination I get errors during stage 1; the zpool that contains the root dataset cannot be imported. This occurs after I enter the correct LUKS passphrase. This made me question if this is at all possible (it should, shouldn't it?). Could some of you please take a look? I documented most of it in the gist here: https://gist.github.com/awesomefireduck/ffea6517042af87b8b7ef6ea1c7d50e3 . If you need more information I'd be happy to supply it. Sincerely, Vince ___ nix-dev mailing list nix-dev@lists.science.uu.nl http://lists.science.uu.nl/mailman/listinfo/nix-dev
[Nix-dev] Using bundlerEnv to create a rails development environment
Hello,
I am trying to use bundlerEnv to create a development environment I'll
use with nix-shell in the context of a rails application.
When I am launching nix-shell, I would like the following to happen:
- having all the needed gems my application depend on installed
- start any dependent services (databases for example) until the shell
is gone
Currently I have the following `default.nix` in my test dev folder:
---
with (import nixpkgs {});
let
project_name = myproject;
ruby = pkgs.ruby_2_2_0;
env = bundlerEnv {
name = project_name;
inherit ruby;
gemfile = ./Gemfile;
lockfile = ./Gemfile.lock;
gemset = ./gemset.nix;
};
in
stdenv.mkDerivation {
name = project_name;
src = null;
buildInputs = [ env postgresql ];
shellHook = ''
set -e;
export PGDATA=/var/dev-srv/pg-${project_name}
export PATH=${env}/bin:$PATH
export GEM_HOME=${env}/lib
if [ ! -d $PGDATA ]; then
initdb
fi
if [ $autostart-postgres ]; then
pg_ctl -D $PGDATA -l ~/code/myproject/log/pg.log start
trap 'pg_ctl -D $PGDATA stop' EXIT
fi
'';
}
---
Which is basically a tentative to smach together multiple stuff I found
for other development environment and bundlerEnv.
This start and stop the postgresql database when I go in nix-shell, but
it does not load all the gems correctly (they are installed, but not all
available to ruby). This is what happen when i call rake in the
nix-shell:
---
Could not find i18n-0.7.0 in any of the sources
Run `bundle install` to install missing gems.
---
Note that I am a total noob when it come to Nix currently, so it does
not surprise me that this is not working!
Can somebody help me on this?
Best regards,
--
