+++ This bug was initially created as a clone of Bug #1287611 +++

Description of problem:

I have /dev/sda1 which is a PPC PRePboot partition and blkid only shows the UUID for it:

# blkid

Version-Release number of selected component (if applicable):
util-linux-2.23.2-26.el7.x86_64

How reproducible:
Always

Steps to Reproduce:
1. Install a ppc64 or ppc64le system.
2. Selected automatic partitioning.
3.

Actual results:
blkid doesn't give us any indication that sda1 is a PRePboot partition.

Expected results:
The opposite. 

Additional info:

I'm working on a test which uses blkid output and this is a corner case which isn't covered. blkid is very handy in bash scripts and we need it to somehow identify PRePboot partitions.
