I think I found at least part of my misconception: the canmount property
is not inherited. After a closer inspection, I get only nested filesystems
mounted with "zfs mount -a", not the one where I actually set
canmount=noauto. That's a bit of a pity, as I would like to set/inherit
the property recursively on a whole subtree, but apparently that's not
possible using a single command.

However, I still fon't get any of the nested filesystems mounted on "zpool
import", they all stay unmounted there. So canmount is (quite unexpectedly
to me) treated differently for "zpool import" and "zfs mount -a".
