expands on #2110

I don't like the idea with URL. Cannot ostree/bootc managaged host install a manual page and DNF simply referring that manual page? I guess the URL is supposed to document how to make a root file system writable.

We repeatedly get reports that DNF is used on disconnected systems and there pointing users to an on-line system is pointless.

I think ideally we have both, but this is easier to get started. We're trying to minimize the amount of churn needed in dnf by planning ahead and conditionally keying off something outside dnf. Also, worth noting that manpages are very often stripped in minimal OS builds (that's the case in FCOS for example).

And of course, we can always improve things in follow-ups when there are less strict deadlines to deal with.
