I am new to zfs and do not understand the reason that you would want to
create a separate file system for each home directory. Can some one explain
to me why you would want to do this?
because in ZFS filesystems are cheap, you can assign a quota or
reservation for each user. you can see how much space they are using
with df /export/home/username or zfs list username no more waiting
for du -s to complete , you can make a snapshot of each users
data/filesystem.
I'm sure they are more but another time
