Darn... But thanks for the answer :)
Being a FreeBSD newbie I'd like to ask: How much of the system would
be needed for booting up ? That is, how much of the system do I _have_
to keep on a non-volume ?
Obviously I'd like to have as much as possible on RAID-1.

How does soft-updates affect the filesystem stability ? If the machine
looses power before/during/after a fsync(), what are the consequences
of using soft updates ?
