I do not know if this is exactly correct but the following did work for
me (anything less would not seem to apply the devfs rules)
devfs_rulesets_from_file /etc/defaults/devfs.rules
devfs_domount /jails/host/dev devfsrules_jail
devfs_set_ruleset devfsrules_jail /jails/host/dev
/sbin/devfs -m /jails/host/dev rule -s 4 applyset
thanks
