Trying to change temporarily the mountpoint of "Music" of my 1.9.4 pool so it does not collide with the one of the 2.2.0 pool with "zfs mount -o mountpoint=/Users/arne/Music194 zfs-extern".
But it does not change the mountpoint.
It stays in the mountpoint as given when the pool is imported ("/Users/arne/Music").
I can only change it permanent with "zfs set mountpoint= ...".
