The ubuntu-cloud template takes that as an optional argument, and will automatically wget the tarball if it doesn't exist. That's what I was suggesting that you do. And to be clear I'm not saying inclusion of the template upstream ought to block on that. > template doesn't do the fetching and setup of the template rootfs. > > I can look into setting up the template rootfs from rpms, or an image > if that is required, but I think its useful also for the template > rootfs to be user specifiable as well.

(Not saying you should go this route, but) the way I address this is to create canonical containers (lvm-based though btrfs-based works too) and then lxc-clone them.
