Public bug reported:
I've observed in livefs build logs that with kpartx 0.5.0-7ubuntu12,
'kpartx -d' is not removing the loop mapping (losetup -d). E.g., build
log diff:
+ kpartx -v -d binary/boot/disk.ext4
del devmap : loop0p1
-loop deleted : /dev/loop0
This doesn't seem to be causing any immediate practical problems because
each livefs build gets a dedicated VM which is torn down afterwards, so
the mappings do not persist. But it's definitely incorrect for these
mappings to persist.
The good build log used kpartx 0.5.0-7ubuntu9. Testing the intermediate
versions, 0.5.0-7ubuntu11 shows the same buggy behavior as 12. 10
clears the loop mapping, but also appears to fail to correctly set up
partitions in my test case so I'm not sure if this bug is present or not
in 0.5.0-7ubuntu10.
