No because it is supported by the system with the btrfs cow / snapshot file system. https://btrfs.wiki.kernel.org You can create your btrfs filesystem, mount it somewhere in your fs, install a distro and then make a snapshot, that will result in a directory. Assign this directory as the rootfs of your container. For each container you want to install, create a snapshot of the initial installation and assign each resulting directory for a container. ------------------------------------------------------------------------------ ThinkGeek and WIRED's GeekDad team up for the Ultimate GeekDad Father's Day Giveaway.
