Ok, I just took some minutes to finally implement it.

(grml-)rebuildfstab supports LABELs and UUIDs now.

One approach is to check all present partitions/filesystems for
their LABELs and if duplicates are found (for example two
filesystems with a LABEL named "TEST") generate just one entry (the
first device found with the label wins when running "mount
/mnt/$LABEL"), this would look like:

  http://grml.org/tmp/gkrellShoot_09-11-06_001808.png

The other approach is to check for label duplicates and use UUIDs
instead for the labels where uniqueness can't be guaranted:

  http://grml.org/tmp/gkrellShoot_09-11-06_002811.png

Both versions add additional information to the fstab-entry so it
should be clear what's going on. Of course all the LABEL/UUID stuff
will be documented. The according /mnt/[$LABEL|$UUID] directories
are created automatically as well, so you don't have to care about
anything at all.

Please let me know what you think about it. I will run some more
tests before grml-rebuildfstab is going online. If we find a
solution most of us like I would prepare a new devel-release so you
can explore all the new development stuff on your own.
