I think it should both delete duplicates, and then error out when two or
more packages with the same name remain. Further, this should take into
account propagated inputs.
I think this is a pretty radical change, though, and I wonder about the
amount of breakage it would create. For instance, it means that one
could create a profile containing both magit-referring-to-git-2.8 and
git-2.9, or emms-referring-to-vorbis-tools-1.0 and vorbis-tools-2.0.
Concretely, that means one will no longer be able to upgrade magit
without also upgrading git, for instance (assuming they live in the same
profile.)
WDYT?
Thanks,
Ludo’.
