Bug#764036: mdadm: /var/lib/mdadm and /etc/mdadm not deleted on upgrade/purge

[Laurent Bigonville]

Package: mdadm
Version: 3.3.2-2
Severity: normal

Hi,

During the upgrade of the package I got the following message:

Unpacking mdadm (3.3.2-2) over (3.3.2-1) ...
dpkg: warning: unable to delete old directory '/var/lib/mdadm': Directory not empty

And indeed "/var/lib/mdadm" was not removed properly, I guess 
"rmdir --ignore-fail-on-non-empty /var/lib/mdadm" should be called after
deleting the files to ensure the directory is properly deleted.

The same thing happens with "/etc/mdadm" when purging the package,
/etc/mdadm/mdadm.conf and the directory is never deleted.

Cheers,

Laurent Bigonville
