This makes sense as long as we don't abuse it. The numbers are there to
apply some amount of order but flexibility is good, and will avoid the
problem of having humongous update files.

I'm fine with allowing DM given that it allows running as non-root
(pretty much the only condition that ldapi wouldn't work), but I think a
full upgrade will fail w/o root given that you are combining the two
commands.

On ipactl, would it be overkill if there is a tty to prompt the user to
upgrade? In a non-container world it might be surprising to have an
upgrade happen esp since upgrades take a while.

With --skip-version-check what sorts of problems can we foresee? I
assume a big warning will be added to at least the man page, if not the cli?

Where does platform come from? I'm wondering how Debian will handle this.

Looks really good.
