What if something identifying the profile (directory name? config file?) inc=
luded info about the Guix revision it was built from? That way a profile wou=
ld be reused if it=E2=80=99s built from the same Guix revision, but if you s=
witch revisions it=E2=80=99d be rebuilt.

I=E2=80=99m not sure how this would interact with a profile built from packa=
ges in multiple channels.=
