"CAN be" isn't very useful. while ZFS provide "virtual partitions" (which
may LOOK good), it doesn't work well with 2 or more pools created out of
partitions not full drives.
my common config on machines with >1 drive is to make gmirror (or
gmirror+gstripe) from first partitions of each drive, to store most common
data, usually EXCEPT huge files, and gconcat from other partitions to
store mostly big files, other rarely used things, copies of other things
then drives seeks mostly within first partition so it's much faster, and i
have unmirrored larger space on second.
with ZFS it is not possible, while it CLAIMED to completely and definitely
remove all these burder about planning disk layouts.
