what do you mean by 'but different'? the actual df output lists this:
# df -h
Filesystem Size Used Avail Capacity Mounted on
/dev/ad4s1a 290M 81M 186M 30% /
devfs 1.0K 1.0K 0B 100% /dev
/dev/ad4s1d 989M 50K 910M 0% /tmp
/dev/ad4s1f 15G 5.0G 8.4G 37% /usr
/dev/ad4s1e 989M 33M 877M 4% /var
/dev/ad4s1g 126G 90G 25G 78% /work
i read it as one disk - ad4 - with one big slice 1 and 5 partitions.
am i wrong? fstab shows same devices.

please elaborate. do you mean that the raided disks will have another
id/name rather than 'ad'?
Not knowing what hardware you have, I would still hazard
that a RAID device will not show up as /dev/adN.
I would guess that the RAID controllers that use cam
might have their devices called by the /dev/daN convention,
but I don't know that.
ok. i guess i'd explore the 'interesting phone calls' one.
if it doesn;t walk like a duck and it doesn;t quack like a duck it must be
some other bird/thing...
I would agree with that.
