I'm planning to implement the reverse approach on my system: have some
sort of rebuild hook commit the state of the repo to a separate branch
and include useful information (nixpkgs version, derivation hash of the
resulting system) in the commit message. This allows greater
reproducibility and provides far more helpful information (a snapshot of
the full config) than simply "repo was dirty".

I'll reply if/when I get this working.
