+Ahh, good catch. I forgot about this conflict as I fixed shadow-utils a

+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.
