Delaying mount of UFS filesystem in ZFS pool

I didn't think of mountlate, that may work. What I ended up doing was
adding the "noauto" option and running a cronjob that checks and mounts
the filesystem.
Unfortunately, I learned that quotas only apply to mount points and not
directories, so I may not be of any use for testing new things in the
near future.
