You would use petercentos rather centos as the template to download, and provide a petercentos configuration that points to your tarball. Obviously you will use your company name in the production version :-)

That's where I'd like to get to eventually. That said, since this is all 
part of an automated process and no one actually runs lxc-create 
interactively (it's all done in Python scripts), it doesn't really 
matter if our custom tar ball gets installed as an official formal 
template. The lxc-create command works quite well using "none" for the 
template, as long as the rootfs is put in place through some other 
means. Since we're transitioning from libvirt to LXC and need to keep 
both frameworks in play for a while, it's easier in our code to install 
rootfs explicitly rather than having lxc-create do it.
