Description of problem:
It would be extremely awesome pony if blkid would show wwid of devices when run..
Version-Release number of selected component (if applicable):
Steps to Reproduce:
The scsi_id(8) is able to read WWID. I'm not sure that we want to duplicate this functionality in libblkid.
IMHO the ideal solution would be to have WWID in /sys/block/<name>/device/ where we already have the vendor and model attributes.
The command lsblk(8) reads WWN from udev database. For example try
lsblk -o +WWN
on Fedora 18. Closing.
