As long as it's not default. One of the most convenient ways to change a user's UID (or multiple users!) is to do an mtree backup, change UID/GID, and then re-apply mtree backup. Every file that the user(s) previously owned will be automatically changed to the new UID/GID for you :-) _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
