The specific requirement here is to prepare for a transition from old PATA ("IDE") drivers to libata-based drivers. libata presents ATA/ATAPI drives as SCSI devices, so hard drive partitions will change from /dev/hdX to /dev/sdX. In preparation for this partition, /etc/fstab and the kernel parameters in boot-loader configs should be changed to specify partitions by UUID or label name so that they work with both old and new kernel versions. There will be a debconf question as to whether this should be done automatically, but it is not appropriate to expect all users to make this change manually.
