Yes I noticed this and I'm not sure I like it.  For example on a test rhel6
build I have a UUID for /boot

[john at dsv03-pv1 ~]$ grep UUID /etc/fstab
UUID=cae1fd8f-acfd-4e46-bd96-8c893c07b54b /boot                   ext3
 defaults        1 2


But where is it getting this from?  It's not the UUID for the filesystem or
(in my case) the md raid device underneath. e.g.

[john at dsv03-pv1 ~]$ sudo udevadm info --query=all --name=/dev/sda1 | grep
UUID
E: ID_FS_UUID=274ea8e2-0bd2-2aab-ab86-3ea6f42c03cb
E: ID_FS_UUID_ENC=274ea8e2-0bd2-2aab-ab86-3ea6f42c03cb
E: MD_UUID=274ea8e2:0bd22aab:ab863ea6:f42c03cb
E: MD_DEV_UUID=117ed612:97cea2cd:2d80c66d:52ade163
