You can't upgrade a slot, portage sees as if they were two different
packages. You can't "upgrade firefox to chrome" either for the same
reason. Instead, you unmerge the slot you do not want and fix everything
that remains (@preserved-rebuild, revdep-rebuild etc)

You haven't yet said which app you are using that won't umount the
camera, so it's a bit difficult to give proper advice. We'd need some
info first?

- what is the app in question?
- relevant USE flags it uses?
- what does it link to?
- does that pp support udisks:2?
