Hi Michael,

Sorry for the delay, I was OFF until yesterday.

udev relies on blkid library to retrieve the ID_PART_ENTRY_* values. Therefore
if they are missing from the udevadm output then they are probably also missing
from the data returned by the blkid library.

To verify that the following commands can be run:

 $ blkid --probe /dev/sda2 -o udev

and also:

 $ udevadm test-builtin blkid /block/sda/sda2
