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? All my Googling gets things about when the file system is read-only and it should not be. I want to go the other way. I see that MicroOS's root is read-only. But I do not want the transactions. I want nothing to survive a restart. Except the original read-only stuff. -- Roger Oberholtzer
