This is the same as what ‘guix package --list-profiles’ returns so it includes non-standard profiles. 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 ‘guix gc’, at least in its current state. In short, ‘guix gc -d’ was introduced precisely so that one doesn’t 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 ‘guix package --list-profiles’ in the hint was actually misguided.) The only things not handled are (1) the system, and (2) non-profile GC roots. I think it’s OK to not mention them in the hint because these are kinda “advanced” features. Thoughts? Ludo’.
