Usually, you want the mountpoint to be one of the inherited properties
-- so set canmount=off instead.

This pattern is used by default already in the installer.  The root
filesystem is created as a BE under zroot/ROOT/default/ but there is
also a zroot/var which has canmount=off to act as a parent to
zroot/var/logs, zroot/var/mail etc. which are not part of the boot
environment but are mounted in the expected locations under /var
