Just upgraded Ubuntu from feisty (7.04) to gusty (7.10). Was a bit touch and go for a moment … got a filesystem check failure on reboot. Miamoto_musashi, my knight in shining armour from #roro, saved the day.
ls -l /dev/disk/by-id/ revealed that my HDs had been remapped from
/dev/sd. The gutsy upgrade had modified all of the standard partitions to use UUIDs, but had failed to update a custom mount I had (
/data -> /dev/hdc1). Changed that over in
/etc/fstab, reboot, hooray we have a winner.
