You mean like showing "/ (/dev/sdb1)" instead of "/"? It's doable..
Might make sense in some cases. FWIW, I'm (or alexl) is going to revisit
most of this before F9 as part of the gio/gvfs hacking. Stay tuned!

I'm failing to see why this question relevant to this discussion? 

I'm simply just asking the Anaconda to a) use UUID instead of LABEL (if
applicable; e.g. some FS's don't have UUID); and b) use some sane labels
by default. The user is still free to edit /etc/fstab to use LABEL=
instead of UUID= and/or relabel his drives or do whatever he wants.
