Package: util-linux
Version: 2.17.2-9
Severity: normal
For some reason this system would not reboot today. I eventually gave up and
re-created the root partition using the squeeze cd and restored from last
nights backup. During this process "/" on md0 became "/" on md125.
All seems well again well but since my orignal boot problem was related to a
missing uuid disk I did a little more investigation. It seems on this system
blkid does not agree with uuids displayed in other tools:
$ cat /proc/mdstat

So far so good except these:
