Couldn't you also do "mount -t devfs -o nonewdev devfs /home/jail/dev"
and then cd /home/jail/dev ; rm $devices_i_dont_want_in_my_jails ?  It
seems that "read my lips: no new devices" should be an option you can
set from the very initial mount so that people can't also figure out
how to get root, remove a /dev entry and replace it with one of their
own.  Come to think of it, there should also be a -o staticdev option
to disallow *any* changes after the initial mount.  That would make
some of our more paranoid sysadmins happy.
