The root mounting code runs well ahead of anything which looks into /etc/fstab; how indeed could it even find fstab if it didn't know where the root partition was? You need to change the kernel's mind about where to find its root partition, something which can be accomplished in a variety of ways. In the case of the boot floppy, we don't even try; we just use MFS for the root partition and mount the CD elsewhere. Of all the options, this is in fact the simplest. - Jordan To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-questions" in the body of the message
