Merge lp:~wt-penguintechs-org/vmbuilder/vmbuilder_add_debootstrap_tarball
From the merge proposal:
This change adds an option to use a prebuilt debootstrap tarball so that one doesn't have to download the packages for every image creation. You can create a debootstrap tarball with something like:
$ debootstrap --variant=minbase --make-tarball=blah.tgz precise /tmp/minprec-chroot
Then you can use it with:
$ ubuntu-vm-builder xen precise --variant=minbase --debootstrap-tarball=/home/wt/projects/tarball_debootstrap/precise_minbase_debootstrap.tgz
The build process has the potential to be way faster when building more than one image.
