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.):
NAME USED AVAIL REFER MOUNTPOINT
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.

I've tested this and agree with it. It should be added upstream as it
makes it simpler to have these extra /mounts. Otherwise you have to
explicitly set them with mountpoint=/usr, /var, instead of inheriting
from the / dataset.
The problems I mentioned were probably before we got the 'canmount'
support in to prevent remounting over /.
