‘guix gc --delete-generations=1m’ deletes generations of both
~/.guix-profile and ~/.config/guix/current.  (When running as root it
does that for all the users.)

I would not recommend ‘guix system delete-generations’ here because it’s
only accessible to root.

IMO hints should remain concise, and I’m afraid this might be too much.
Also, /var/guix/gcroots/auto is an implementation detail; I’d recommend
running ‘guix package --list-profiles’ instead.

WDYT?

Thanks,
Ludo’.
