The devel version of libblkid from util-linux-ng supports partition tables
parsing, and the partition name (GPT nad Mac) and partition UUID (only GPT)
are exported to udev. For example:
# blkid -p -o udev /dev/sdb1
ID_PART_ENTRY_SCHEME=gpt
ID_PART_ENTRY_NAME=ThisIsName
ID_PART_ENTRY_UUID=bc10cf1d-7e63-524c-8203-087ae10a820b
ID_PART_ENTRY_TYPE=a2a0d0eb-e5b9-3344-87c0-68b6b72699c7
ID_PART_ENTRY_NUMBER=1
In my TODO list is to support partition identifiers for standard
operations like mount/fsck, something like:
# mount PARTUUID=bc10cf1d-7e63-524c-8203-087ae10a820b /mnt
or
# mount PARTLABEL=ThisIsName /mnt
