Ahh, good catch. I forgot about this conflict as I fixed shadow-utils a
week or so ago. I'll take care of it.

Well I do not think doing such a move on an in-use filesystem is a
particularly good idea (especially for the /var/run bit which makes use
of several socket files for IPC (think all of dbus breaking).

So doing such a conversion like this does not seem like a good idea to
me. This is why it is done in the initrd before the switchroot or in the
installer when the system is mounted under /mnt.

That's my opinion on it. One thought: we could put it in  a %post script
provided it was protected via a check on the $DURING_INSTALL variable
and thus only ran in the installer context.
