A setup script and accompanying files to set up an overlay root filesystem on a Debian like OS on a RaspberryPi or similar computer. But it even works on a standard Debian system. Overlay root means the underlying files system (usually an SD card on a RaspberryPi) is mounted read only and all changes happen in a ram disk overlay. That way, you can power off your Pi (unplug power cable) any time without risking file system corruption on the SD card.

Martin "Wimpy" Winpress once described the process in which Jorge Castro setup his Silverblue OS (Fedora) system to be more "at home" like putting on a pair of comfy slippers... This script is named after that process.

(Catch the interview here https://www.youtube.com/watch?v=vhaQPAuOi9E).

He essentially used a script to do so (https://github.com/castrojo/ublue) and I wanted to learn how I can get my own started....and learn this process all the while.

P.s. I'm a noob - so don't expect much here lol ;)
