all these symptoms sound like your upgrade went horribly wrong. I've
seen preupgrade mash up a box by half upgrading like that. It's the
main
reason
I don't think preupgrade is actually safe to use yet.

Preupgrade's process is to depsolve - using the same method anaconda
does, download the pkgs it solves out. Put them in a cachedir. Download
a kernel and an initrd, Setup a ks.cfg. then reboot the machine and
allow anaconda to do the install.

Specific issues we've had with preupgrade are related to not being able
to find a mirror and/or not being able to get pkgs.

Mine were
* preupgrade running out of diskspace on / when trying to fill
/var/cache/yum (my "/"'s tend to be minimized/small)

You're not blaming Preupgrade for the partition being too small, are you?

Well, to some extend, I am blaming it, because
a) filling '/' may easily kill a system and may easily cause further damage
(processes running in parallel to preupgrade might be malfunctioning due
lack of diskspace).

b) I expect an installer to be able to check whether sufficient space is
available in advance, rsp. not to leave a system in an unusable state in
case of something going wrong.

In BZ https://bugzilla.redhat.com/show_bug.cgi?id=503183
I questioned whether using /var/cache/yum is a good choice for preupgrade's
package cache. Though I meanwhile know that this BZ is was a side-effect of
the nfs-parser bugs in anaconda, I still think using /root or /tmp would be
better choices.

No, some people (me included) use tmpfs for /tmp , so this would
result into reboot, no packages found (if it did not hit a space
problem either).
Your problem, if you are using a non-reboot persistant /tmp

On my machines, various subdirs of /var are nfs mounted and spread across a network.

/root is not supposed to be used by random apps.
This is not a random app permanently using a filesystem.

It is the user "root" running an application to set up a personal temporary filesystem to be used exclusively by him.
