The root Filesytems doesn't really change.
In general if you don't edit something in /etc or add accounts you can
even be happy with a readonly /.
I can't see any needs for mirrors beside that the host should keep running
in case of a disk failure. A simple backup of the small /etc is sufficient.

You don't have to find a new / disk if you already created one.
A mirror would allocate it anyway.

Nevertheless Greg showed me an df output with a mirrored / filesystem but
as I usually have stone old drives (90M drives are more than enough ;) for
/ I never tried it myself because I don't own 2 identic of them.
I don't know if it was plain vinum or some magic.
