I built a system like this (even to the extent of having /usr/src on
UFS) for that reason.  My experience has been that the gmirrored UFS
has caused more data-related problems than ZFS (ZFS has been
responsible for more hangs and panics but survives them far better and
ZFS in recent 8-stable has fixed those problems).  In particular, it
looks like I'm losing writes to one of the disks in my gmirror (and
they are identical disks, though with different firmware) under some
circumstances on shutdown.

I'm in the process of rebuilding that system and, based on my
experiences with that system and some other ZFS root systems, will be
converting it to use ZFS root.
