SVR4 does this, too. I hate it. What happens when you remove a device, or one dies? If I have disks at SCSI IDs 0, 1, and 2, and disk 1 dies, then the system will see disk 2 as disk 1 at boot time, and all of my filesystems will fail to get mounted or get mounted from the wrong disk. Who could possibly think that this is a good idea? What is wrong with always having the SCSI ID in the name/minor-number? It seems the ONLY correct way to do things. -- David Wexelblat <dwex@mtgzfs3.att.com> (908) 957-5871 Fax: (908) 957-5305 AT&T Bell Laboratories, 200 Laurel Ave - 3F-428, Middletown, NJ 07748 XFree86 requests should be addressed to <xfree86@physics.su.oz.au> "Shining, flying, purple wolfhound, show me where you are."
