Exton|OS Light Live CD is based on Ubuntu 16.10 Yakkety Yak 64 bit and Debian Stretch/Sid. Exton|OS Light's ISO file (of 970 MB!) is a ISO-hybrid, which means that it can very easily be transferred (copied) to an USB pen drive. You can then even run Exton|OS from the USB stick and save all your system changes on the stick. I.e. you will enjoy persistence!
