I checked (guix scripts gc). =E2=80=98guix gc -d=E2=80=99 operates on all = the profiles among the roots returned by =E2=80=98gc-roots=E2=80=99. This is the same a= s what =E2=80=98guix package --list-profiles=E2=80=99 returns so it includes non-standard profil= es. You can check on your machine. It does not include non-profile GC roots, and in particular it does not include system generations. Deleting a system generation involves reinstalling the bootloader (or its config file), so it cannot be done from =E2=80=98guix gc=E2=80=99, at l= east in its current state. In short, =E2=80=98guix gc -d=E2=80=99 was introduced precisely so that one= doesn=E2=80=99t have to search for all the profiles, and this hint was added in the same patch series I think. (So my earlier advice to mention =E2=80=98guix packa= ge --list-profiles=E2=80=99 in the hint was actually misguided.) The only things not handled are (1) the system, and (2) non-profile GC roots. I think it=E2=80=99s OK to not mention them in the hint because the= se are kinda =E2=80=9Cadvanced=E2=80=9D features. Thoughts? Ludo=E2=80=99.
