I concur with all of the suggestions to use blkid. I've had it come back
to bite me a number of times in large volume sets (raid or lvm).
I've taken drives out of machines and forgotten which order they were
in. Using the UUID this will not matter unlike if you reference the
physical path /dev/{s,h}dX. I've also had things like usb drives
or usb keyboards shift the physical path a letter or two and this
causes absolute mayhem on things like file servers.

why blkid's are used, though names still work (sdXX etc).

The benefit of using the label is that you are not 'hard coding' the
system to mount a disk at a specified location or can be used as an
alias of sorts. Using a label can be more flexible in dynamic
environments where things can change.
For example:
There could be an environment where USB storage is randomly inserted
in the system and rather than have the user's work through fdisk and
decide which drive is which, label each partition with a label and
have them mount it that way.
I have seen FC attached drives from a SAN go a bit crazy with which
device name they show up as that day (sdX, sdY, sdZ) due to the order
they were loaded in and labels can also help in that scenario (though
that is just a workaround to the 'real' issue).
If you are on a desktop system and don't notice any problems I would
say that you can use whatever your heart desires. I'm interested to
hear if anyone else has other things to say as well since I have never
really had a reason to use blkid.

*Subject:* adding to fstab
All, I have created a new partition on a spare drive and want to add
it to the fstab. I basically see three(3) different ways to do it. All
work but what is the preferred way.
1. Use Blkid
2. Use Label
3. Use physical device (/dev/sdb1)
All seem to work fine.Any preference?
