They have different minor numbers, and that's what counts to mount(8): finrod@saers /dev$ ll sd0*a brw-r----- 1 root operator 4, 0 May 20 1997 sd0a brw-r----- 1 root operator 4, 0x00020000 Sep 20 16:17 sd0s1a brw-r----- 1 root operator 4, 0x00030000 Sep 20 16:17 sd0s2a brw-r----- 1 root operator 4, 0x00040000 Sep 20 16:17 sd0s3a > So, just update /etc/fstab and /dev, right?

If you can successfully mount other file systems, create a temp directory on any local writable fs, get a fresh copy of MAKEDEV from /usr/src/etc/etc.i386, create a device node for your root fs and mount it: # cd /var/tmp # mkdir dev # cd dev # cp /usr/src/etc/etc.i386/MAKEDEV . # sh MAKEDEV da0s2a # mount da0s2a / Any local filesystem you can write to will do the job; disk, floppy, OD, MFS, whatever. Even better, if you have a live FreeBSD CD-ROM, you can use the device nodes on it provided you have a mount point for the CD-ROM (unless you've already mounted other file systems, /usr, /var and /mnt should be available) DES -- Dag-Erling Smørgrav - dag-erli@ifi.uio.no To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-current" in the body of the message
