Luis Felipe,

I think that would be very helpful.  I'm trying to think of a 
concise, correct, but actually useful definition of profiles for 
someone not already familiar with them or Guix.

Out of curiosity: how do you intuitively understand profiles, as 
someone who's used Guix for a while?

I don't think we should document GUIX_PROFILE.  It's not part of 
the definition of Guix profiles.  It should not matter to users 
nor should they rely on previously observed behaviour.  AIUI there 
are no supported ‘use cases’, beyond copy-pasting Guix error 
messages...

...so this part isn't unexpected.

Kind regards,
