Cannot mount (encrypted) filesystems

[herrernst]

I have a pool created with ZFS on Linux with encrypted filesystems, but unfortunately I cannot mount them on O3X.

sudo zpool import -o readonly=on tank

zfs list
NAME                                             USED  AVAIL  REFER  MOUNTPOINT
tank                   1.64T   116G   102M  /Volumes/tank
tank/encrypted           78.2G   116G  67.3G  /Volumes/tank/encrypted

zfs mount
tank   /Volumes/tank

zfs mount -l tank/encrypted
cannot mount '/Volumes/tank/encrypted': failed to create mountpoint

I've tried with both zfs-1.9.0 and zfs-1.9.1-rc1 on latest 10.14 Mojave.
