What if something identifying the profile (directory name? config file?) 
included info about the Guix revision it was built from? That way a profile 
would be reused if it’s built from the same Guix revision, but if you switch 
revisions it’d be rebuilt.

I’m not sure how this would interact with a profile built from packages in 
multiple channels.
