pfSense

Old ZFS layout (pfSense 2.5.2):

# mount
pfSense/ROOT/default on / (zfs, local, noatime, nfsv4acls)
devfs on /dev (devfs, local)
pfSense/cf on /cf (zfs, local, noatime, noexec, nosuid, nfsv4acls)
pfSense/var on /var (zfs, local, noatime, nfsv4acls)
pfSense/home on /home (zfs, local, noatime, nfsv4acls)
pfSense on /pfSense (zfs, local, noatime, nfsv4acls)
pfSense/tmp on /tmp (zfs, local, noatime, nosuid, nfsv4acls)
pfSense/cf/conf on /cf/conf (zfs, local, noatime, noexec, nosuid, nfsv4acls)
pfSense/var/cache on /var/cache (zfs, local, noatime, noexec, nosuid, nfsv4acls)
pfSense/reservation on /pfSense/reservation (zfs, local, noatime, nfsv4acls)
pfSense/var/db on /var/db (zfs, local, noatime, noexec, nosuid, nfsv4acls)
pfSense/var/empty on /var/empty (zfs, local, noatime, nfsv4acls)
pfSense/var/log on /var/log (zfs, local, noatime, noexec, nosuid, nfsv4acls)
pfSense/var/tmp on /var/tmp (zfs, local, noatime, nosuid, nfsv4acls)
tmpfs on /var/run (tmpfs, local)
devfs on /var/dhcpd/dev (devfs, local)
devfs on /var/etc/named/dev (devfs, local)

After selecting ZFS (auto) and proceed to disk formatting, an errors occurs:

cannot mount '/mnt/tmp': failed to create mountpoint filesystem successfully created, but not mounted

cannot mount '/mnt/pfSense': failed to create mountpoint property may be set but unable to remount filesystem
