Mounting by UUID provides a stable device path to the appropriate
device. Stable as in "the device will be always the right one". Why
it does not work on your box is strange, but let's find out what's
going on.

A very good question. :) I'm not aware of any relevant changes in
grml packages.

Can you please provide me the /etc/fstab you have been using so far
and which does not work any longer? When booting into your system
using the "old /dev/sda4", can you please provide output of:

  ls -la /dev/disk/by-uuid/

And finally: what's inside your /boot/grub/menu.lst or
/etc/lilo.conf (depending on the bootmanager you are using)?

You can find the original reference file as
/etc/runlevel.conf.hdinstall - can you please give it a try to check
booting via UUID using this file? (Make sure you back up your
original/old file.)

Yes, there's an according dialog within grml2hd, you can run it
later on too by invoking 'grml-setservices'.
