It was true, yes, but I don't think it is now. Although, I can't find a link
ATM.

Yes. It is a bit messy IMHO because it is being maintaned by several people...
So, I always manually create my containers, but then again, I always have a
config lying around.

This is supported.

Yeah, I kinda dislike these "daemon + privileged group" things -- reminds me of
polkit.

With lxc, you'll need to have a container running and connect to it via SSH or
VNC. For me this is OK because my build container is on a desktop and I usually
access it from a laptop...
