Excuse me for the maybe silly question, but WHY is this done? It's the next step in the very slow process of divesting some of the old design decisions from the 386BSD days. > I mean...

I'm sorry - you're currently taking advantage of a misfeature that is going to disappear very soon. The DEVFS/SLICE code explicitly disavows any knowledge of the "compatability" slice. > /dev/xd0a / ufs ... > /dev/xd0e /usr ufs ... > > Also, on my other machine I have a SCSI disk for freebsd, and a IDE disk > for Win95.

So... will I need "sd0s1a" on that, > or just "sd0a"? The changes I have made *only* affect the boot device. The remainder of the "compatability slice" implementation remains. Note, however, that when you move to DEVFS, there will not be any sd0[a-h] nodes *in* /dev/, so you wouldn't be able to mount them even if you wanted to. -- \\ 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
