[Nix-dev] hydra and nixos versions/commits at hydra.nixos.org

[Tomasz Czyż]

Domen,

do you know what's the strategy for hydra in nixos? Looks like module file
is not imported from hydra but is copied/prepared separately in nixos. That
means there are two module versions but one code base.

Will hydra module be moved to nixos? If not, maybe would be better to just
import it from upstream?

Is strategy (to keep modules inside nixos for external packages, even those
with nix modules) the way to go for all other projects? If yes, could you
explain why or point to some explanations?
