This may cause unwanted effects. For example, the rule "devfs fd hide" hides an entry /dev/label/fd/label. -- Jaakko _______________________________________________ freebsd-bugs@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-bugs To unsubscribe, send any mail to "freebsd-bugs-unsubscr...@freebsd.org"
