Hello Guix!

This patch series is mostly about making it easier to free space:
‘guix gc --delete-generations’ deletes old generations of all the
user’s profiles prior to collecting garbage.

For consistency, ‘--delete-generations’ is aliased with ‘-d’, so
‘-d’ is repurposed (until now it was an alias for ‘--delete’).

Thoughts?

Ludo’.

Ludovic Courtès (5):
  Add (guix store roots).
  guix gc: Add '--list-roots'.
  profiles: Add 'generation-profile'.
  guix gc: Add '--delete-generations'.
  scripts: GC hint suggests 'guix gc -d 1m'.
