Bug#771971: dpkg hangs installing "init" during upgrade from wheezy to jessie

["Dominik Schäfer" <schaedpq@gmail.com>]

Hello Steve,

I had the same issue with hanging dpkg as well on my VM. However: on i386, not
amd64, and I did not remove/purge any packages before. Also, I used aptitude
safe-upgrade (instead of apt-get).
After quite some time I killed the hanging dpkg process (which used 100% CPU)
and apitude continued. I later issued 'dpkg --configure -a' (which rebuilt the
man-db), 'apt-get -f install' and continued with 'aptitude full-upgrade'.
The result in my case was a non-booting system because init segfaulted.
I then restored the image from before the upgrade.

Bye,
Dominik
