I'm telling you that this constitutes "having trouble". 8) $root_disk_unit should only be required if you have a discontinuity in the chain of devices from bios disk 0x80 to your root device. It would help *immensely* if you were a little forthcoming with eg. what it is that you have to set $root_disk_unit to. Also, as I've tried to make clear here, changing the /etc/fstab entry for / is *WRONG* and if you find yourself having to do this it's because something is screwed elsewhere. Again, please *ensure* that your loader is fully up to date. So far everyone that's reported problems has been using an out-of-date loader. -- \\ 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-hackers" in the body of the message
