Description Pavel Holica 2013-09-13 08:53:36 UTC 
Description of problem:
blkid shows devices as /dev/block/$MAJOR:$MINOR.

Version-Release number of selected component (if applicable):
util-linux-2.23.2-4.el7.x86_64
RHEL-7.0-20130912.0 x86_64 Server

How reproducible:
randomly

Steps to Reproduce:
1. On installed system (any partitioning) run blkid

Actual results:
# blkid 
/dev/block/252:2: UUID="wP1zvZ-OBEI-9zpZ-ULoG-esqa-2ug2-4fHmzJ" TYPE="LVM2_member" 
/dev/block/253:1: UUID="7edffcca-af7d-47c8-8cd4-72f2de2f8697" TYPE="xfs" 
/dev/block/252:1: UUID="65242ccc-4c22-41f1-a3d2-5382ac6fe192" TYPE="xfs" 
/dev/block/253:0: UUID="37ed801d-fae8-4632-b2d9-2d83a9d2fcaa" TYPE="swap" 
/dev/sr0: UUID="2013-09-12-05-22-36-00" LABEL="RHEL Server 7.0" TYPE="iso9660" PTTYPE="dos"

Expected results:
This seems to happen only after first boot after installation.

I'm going to clove this report, it seems non-reproducible in normal environment.

Comment 4 Brian Lane 2016-05-25 22:21:21 UTC 
/run is mounted on tmpfs, how is this cache being copied between the installer environment and the first boot?

Wouldn't it be safer if blkid started with a clean cache on each boot? I'm sure that anaconda isn't the only thing using blkid in the initrd (eg. dracut).
Comment 5 Karel Zak 2016-05-26 10:31:03 UTC 
Not sure what is asking libblkid for devices by the symlinks, but I have improved libblkid to be more robust and canonicalize the paths to keep the cache without the symlinks.

Upstream commit 924c93d9df118338fd54cd73b4a45ccddc4ac103.
