First of all, thank you very much for the good work with this port. I'm sure it's changing the life of a lot FreeBSD system administrators!

In my setup I have the following layout (several datasets for /usr, /var, etc.):

sys                   1.55G  18.0G    31K  none
sys/ROOT               532M  18.0G    31K  none
sys/ROOT/default       114K  18.0G   250M  /
sys/ROOT/default/tmp    22K  18.0G    38K  /tmp
sys/ROOT/default/usr     1K  18.0G   245M  /usr
sys/ROOT/default/var  48.5K  18.0G  36.4M  /var
sys/swap              1.03G  19.0G    16K  -

At this moment the utility does not seems to be able to manage this scheme, since it sets the mountpoint property as "legacy" for all datasets under the root, thus preventing to automatically mount any subdirectory at boot.
I've tested this simple solution (to let do the job to the canmount property), and it seems to solve the problem without affecting the behavior when all system folders are located under a single root dataset (please see the patch below). I'd be glad if you'll include it in the next port revision.

I'm at your disposal for any further detail.

Best regards.
