Short exercise:
| $ whoami
| mlaier
| $ zfs list
| NAME USED AVAIL REFER MOUNTPOINT
| tank 104K 228G 19K /tank
| tank/mlaier 18K 228G 18K /tank/mlaier
| $ zfs allow tank/mlaier
| -------------------------------------------------------------
| Local+Descendent permissions on (tank/mlaier)
| user mlaier create,destroy,mount,snapshot
| -------------------------------------------------------------
| $ zfs create tank/mlaier/test
| cannot mount 'tank/mlaier/test': Insufficient privileges
| filesystem successfully created, but not mounted
This is obviously due to the check in vfs_mount.c patched line 851:
if (jailed(td->td_ucred) || usermount == 0) {
the question is, should this be tuned to allow for the finer grained zfs
permissions to take effect or will we force usermount to use zfs allow mount?
