Disabling Disk UUIDs on Debian 6.0 Onwards
Debian 6.0 onwards uses UUIDs (which are symlinks in the /dev/disk/by-uuid
directory) by default instead of traditional /dev
disk names. This can be awkward on a system with removable drives which get
changed often.
UUIDs can be disabled by editing /etc/fstab to use standard device names.
Grub also needs to be reconfigured.
With grub-pc (the default grub version) edit /etc/default/grub and
uncomment the GRUB_DISABLE_LINUX_UUID=true line.
It may also be necessary to add the following to /etc/grub/default:
GRUB_CMDLINE_LINUX="resume=/dev/sdXY"
where /dev/sdXY is the swap partition.
Don't forget to run update-grub after making changes.
With grub-legacy, the /boot/grub/menu.lst file can be edited manually
to use a standard /dev name instead of a UUID for the root filesystem. Note
that every time update-grub is run this file will be rewritten with the old
UUIDs, so it's a good idea to keep a copy of the edited file.
