I have Leap on a Raspberry PI. I think my question, however, is generic to all Leaps.
I would like to make the OS image read-only, with any changes being in RAM and discarded when the system is restarted.
I have seen things where people collect all the writable files to a RAM disk and then replace them in the OS with symbolic links to the RAM disk. While doable, this seems like a fragile way to do this.
Is it possible to change how the existing file systems are mounted (/etc/fstab), and add a RAM file system that gets all the changes?
I think this is how e.g. Knoppix works/ed - a fixed image and a ram file system, combined with unionfs. Probably also how our Live images work. -- Per Jessen, Zürich (10.6°C) Member, openSUSE Heroes (2016 - present) We're hiring - https://en.opensuse.org/openSUSE:Heroes
