Yup - same issue I had a few days ago.

However it also helped me yesterday too when I had been given a vmware 
instance to extract some data from - I manged to unpack it into a regular 
filesystem, then on a whim, I decided to run it up under LXC - it kicked 
off udev which mknods, so letting it do that make it work OK - actually 
work very OK after I tweaked a few things in the startup scripts to stop 
it grabbing the console, so much so that the people I was doing it for 
want to keep it going for a while rather than extract the data and import 
it into their new system - it turned out to be an FC11 image - my host is 
Debian!
