vagrant-lxc base boxes

Although the official documentation says it is only supported for VirtualBox environments, you can use the vagrant package command to export a .box file from an existing vagrant-lxc container.

There is also a set of bash scripts that you can use to build base boxes as needed. By default it won't include any provisioning tool and you can pick the ones you want by providing some environment variables.

For example:

git clone https://github.com/fgrehm/vagrant-lxc.git
cd vagrant-lxc/boxes
PUPPET=1 CHEF=1 sudo -E ./build-ubuntu-box.sh precise amd64

Will build a Ubuntu Precise x86_64 box with latest Puppet and Chef pre-installed, please refer to the scripts for more information.
