Is there any good online source for how to use a Debian pbuilder under
ubuntu, you can link to? This should be better than a VM for me.

Thanks for all the info. I'm gonna try to go down this path instead.
Seems it is the best way to get updates to the development branch of
ubuntu, and like you say, debian benefits as well.
