Bug#398088: dpkg --purge mdadm not purging /etc/mdadm/mdadm.conf

[Fabrice Lorrain]

Package: mdadm
Version: 2.5.5-1
Severity: normal


Hello,

This is related to BTS #398084.
After a fresh install of mdadm, dpkg --purge does not purge /etc/mdadm/*
as expected.

~$ LANG=C ls -l /etc/mdadm
ls: /etc/mdadm: No such file or directory
$ LANG=C sudo aptitude install mdadm

normal install here, see #398084.

$ cat /etc/mdadm/mdadm.conf 
# mdadm.conf

# Please refer to mdadm.conf(5) for information about this file.
#

# by default, scan all partitions (/proc/partitions) for MD superblocks.
# alternatively, specify devices to scan, using wildcards if desired.
DEVICE partitions

# auto-create devices with Debian standard permissions
CREATE owner=root group=disk mode=0660 auto=yes

# automatically tag new arrays as belonging to the local system
HOMEHOST <system>

# instruct the monitoring daemon where to send mail alerts
MAILADDR root

# definitions of existing MD arrays

$ LANG=C sudo dpkg --purge mdadm

Purging configuration files for mdadm ...

$ ls -l /etc/mdadm/
total 4
-rw-r--r-- 1 root root 668 2006-11-11 18:28 mdadm.conf

And mdadm is playing with initrd again which is uneeded/wanted (#398084).
