This is exactly what’s currently implemented if you look at
~/.guix-profile/manifest, under ‘provenance’.

Like zimoun writes, it would be nice to have some sort of a “describe”

Actually ‘guix describe -p ~/.guix-profile’ works but doesn’t display
anything useful.  We could fix that by recognizing the kind of profile,
