I wrote previously in this thread :

This is because the UUID is only part of filesystem metadata and cannot 
be used to specify a device not containing a filesystem, such as a whole 
partitioned disk. Whole partitioned disks are not present in 
/dev/disk/by-{label,uuid}/.

If LILO's boot sector was located in a primary partition boot record 
(PBR) instead of the disk MBR, you could use the partition's filesystem 
UUID in lilo.conf. Of course this requires to write a standard boot 
program in the MBR and set the partition boot flag.

>Thinking of switching to grub2 to avoid these problems.

I also wrote previously in this thread :

This issue is not specific to lilo. It would affect grub-pc updates too, 
because the boot device is specified by device id.

For example on my system :
$ debconf-show grub-pc
(...)
* grub-pc/install_devices: /dev/disk/by-id/ata-WDC_WD1200BEVE-00WZT0_...

The issue would be happen less often - only when updating the grub-pc 
package instead of on any kernel update - but it would still happen.
