How do I get full debug output?

Good.

Same happens on unstable. And I have linux-container installed:

root at test2:~# dpkg -s linux-container
Package: linux-container
Status: install ok installed


Also, a bit unrelated, is it possible to get dummy interface inside a
container?

root at test2:~# lsmod |grep dummy
dummy                  12712  0
root at test2:~# ifconfig dummy0
dummy0: error fetching interface information: Device not found
