It is originally based upon and derived from Debian. As such, it continues to share many of the same upstream roots.
The following method creates a Live Ubuntu USB that utilizes a compressed Squashfs file system. See How to Fully Install Ubuntu on USB, if you'd rather install and run Ubuntu from an external drive using a method that works exactly like it would running from an internal drive.
