[Nix-dev] mix and match

[Moritz Angermann]

Hi,

I want to build a nixos based on 15.09, but use gitlab
from master. Thus I basically want to use the 15.09
channel and layer gitlab[1] at 1cd99b1 and the gitlab
service[2] at 38579a1 at on top of it.

I’ve asked this today on IRC already.  And the proposed
solution is to use my own nixpkgs-channels clone and
apply patches as need, thanks joachifm!

Yet this seems like it’s easily going to end up in a
mess and I though I’d ask here again. Is there any
other recommended way?

Cheers,
Moritz
