This was a straight upgrade using freebsd-upgrade. I don't do source builds anymore, since freebsd-upgrade was "reliable". What is the boot loader expecting to find in /etc/fstab ? I can boot live media and fix that, if I know what to change it to. Thanks, Bill Dudley This email is free of malware because I run Linux.
