[Warren Turkal <wt@xxxxxxxxxxxxxxxx>]

Warren Turkal has proposed merging lp:~wt-penguintechs-org/vmbuilder/vmbuilder_add_debootstrap_tarball into lp:vmbuilder.

Requested reviews:
  VMBuilder (vmbuilder)

For more details, see:
https://code.launchpad.net/~wt-penguintechs-org/vmbuilder/vmbuilder_add_debootstrap_tarball/+merge/151893

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.
