The question is about hierarchical jails. Having jail_NAME_devfs_enable="YES"
inside a jail is not working as devfs is not a jail friendly fs. So I mount
devfs as part of the /etc/fstab.MYJAIL on 'root' but then by default the whole
devfs will be visible to child jails.

So my two questions are really:
        - In rc.conf is there a variable I can use to pass children.max=N to
          one of the jails?
        - Is there a way to have a 'default' devfs rule for certain
          mountpoints? E.g. can a rule be applied at mount time?
