Package: kvpm
Version: 0.8.6-3
Severity: critical
Tags: upstream patch
Justification: causes serious data loss
Dear Maintainer,
If a partition with data on it is moved by kvpm and that same disk
has another partition which is mounted then sometimes the data on the
moved partition is scrambled. Even the filesystem is gone. Unmounting
the other partition is the only fix for the problem.

partition while the disk has other partitions mounted.
