[Nix-dev] Installing hydra as a nixos module

[Philip Lykke Carlsen]

Hi there.

I'm trying to make a local installation of Hydra to try it out as my CI 
system. However, I'm a bit confused about how to best integrate it with my 
nixos installation.

At first I tried to just 'nix-env -i hydra' after having added and updated the 
http://hydra.nixos.org/jobset/hydra/trunk/channel/latest channel, and that 
went somewhat well.

But then I came across the option to install it as a module in nixos after a 
conversation on IRC. However, as I'm still a bit new to nixos, I'm at a loss 
of how to actually include hydra in /etc/nixos/configuration.nix (which is what 
I presume that I am to do..)

I was hoping someone here would know how :-)

Kind regards, plc
