This is Xenialpup 7.5, the version of Puppy Linux I am using. I am running the UEFI version. http://blog.puppylinux.com/xenialpup-released
If you want a live Linux with persistence, pickings are slim. I couldn't get a persistent version of Ubuntu running. I don't think Knoppix does persistence. So I turned to a distro I first ran more than 10 years ago: Puppy Linux, which was built for persistence.
