No, for the reasons I wrote a bit later: When the machine boots multi user
with a bare bones setup, in particular without networking or even accepting
serial line connections, it is no problem if it is called "myhost", with
"mydomain.org" as domain and no IP address. Note that this is not a real
multi user state in the sense "multi user" is usually interpreted, but
rather a standalone mode, set up correctly, however, for entering all the
necessary configuration data.
In principle, it should be possible to realize this while not yet in
multi user mode, see below.

Don't misunderstand me here: I'm not against the idea, but I oppose the
current implementation. If booting stops at a point where filesystems are
not yet checked and mounted and / is still mounted read-only, then it is
unnecessariliy difficult for most non-gurus to actually perform the setup.
People then ask for help and are told to just set rc_configured=YES, and
that turns the whole thing into a useless nuisance.

Yes, indeed. This would be even better. How about the following:
1. Whatever the setting, booting proceeds until filesystems are checked and
mounted read/write. Then, rc_configured is checked and, if not set to YES,
the configuration script is called. Once all information is entered and
confirmed, the system boots multi user. Otherwise, it starts a shell to let
an expert user make additional changes (s)he wants.

The script could even take care of this, but an ifconfig.sample etc. would
still be good.
