This is a very good idea, I would like to get that too, but it's a bit more work than the "auto"-mounting. -- Andriy Gapon _______________________________________________ [email protected] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[email protected]"
