hmm, no I don't remember and can't find it. cjwatson may remember.
@xlyz,
you'll need to at least allow the containers to have mknod in the container for udev to succeed. (You can do that using the container's config file). But I was actually suggesting just doing the upgrade in a chroot as part of initial setup.
It should be possible to automate this as a part of the ubuntu template. Please feel free to open a bug against lxc to make that happen.
