@AbbieNormal@social.device5.co.uk @vidak@zoinks.one It’s an experiment in making a desktop Linux with immutable system directories.
It’s kind of how containers or Alpine Linux in data mode work. There is a base, and there are layers on top of the base which contain software additions and configurations. For updates, the base gets written then switched on reboot, and all of the layers get applied to the new base.
