Just a note - there were many attempts to add jail_myjail_name="myjail" 
variable to rc.conf but it was always denied with same answer:
There is no reason for it, it can be done by jail_myjail_flags=" -n myjail"

See this PR http://www.freebsd.org/cgi/query-pr.cgi?pr=conf/150599 and 
freebsd-jail_at_ archive.

Maybe it will change in jail v2 land or jail config by Jamie...
