Package: kpartx
Version: 0.7.4-3
Severity: important
Hi,
If I execute the following testcase:
#!/bin/bash -xe
IMAGE_PATH=bug.img
truncate -s 3608M "${IMAGE_PATH}"
/sbin/sfdisk "${IMAGE_PATH}" <<-__EOF__
4M,512M,L,*
516M,512M,,
1028M,512M,,
1540M,,E,
,64M,,
,64M,,
,,,
__EOF__
sudo kpartx -l "${IMAGE_PATH}"
sudo kpartx -a "${IMAGE_PATH}"
sudo kpartx -d "${IMAGE_PATH}"
then kpartx won't cleanup its loop devices:
$ ls -l /dev/loop* /dev/mapper/

this is really problematic, because you can't invoke kpartx twice - in
some scripts, the loop devices indices become wrong.
