Package: mdadm
Version: 2.6.3+200709292116+4450e59-1
Severity: critical
Justification: breaks the whole system
Today I installed a package update for mdadm.

This could cause an unbootable system in case of rootfs on a mirror and
a faulty mdadm.conf. This is not my situation, but this is why i filed
a critical bugreport.
I did a rebuild to get a backtrace w/ symbols:
export DEB_BUILD_OPTIONS=nostrip
apt-get source -b mdadm
dpkg -i mdadm_2.6.3+200709292116+4450e59-1_amd64.deb
