It makes sense to me that md0 should be reported twice with the same UUID, but
surely the underlying hardware should be getting a unique UUID?
The use of LABELs is attractive, but I notice you have the same label for sda5
and sdb5. This means you cannot intervene on "msi85:0tmp". You have to specify
sda5 or sdb5.
