Since this entire thread came about due to a device name change, and given that the last major upheaval in this domain was over a similar change, I'd say that was wishful thinking in the least. > Note that there is, or should be, no problem here with the BIOS drive > number.

This presupposes that the configuration file is always right, ie. that it correctly describes the location of the disk. This isn't really a valid premise, and in any case does no better than to duplicate the 'last mounted on' field in the filesystem itself. I'm not sold, sorry. This isn't sufficiently automatable, nor does it remove the room for massive user error that I for one fear greatly. -- \\ Sometimes you're ahead, \\ Mike Smith \\ sometimes you're behind. \\ mike@smith.net.au \\ The race is long, and in the \\ msmith@freebsd.org \\ end it's only with yourself. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
