I am looking for a read only script for stretch (not lite). I have found a lot of things these last few days but nothing that will do read only for stretch and work with the latest OF from git. I do have a USB stick in the pi to read and write changing files, and it is faster than the SD card so I can redirect swaps and whatever I need to there.
The main reason is I want this device to be able to be hard unplugged, there is not really a good way for a shutdown sequence. If anyone has any good pointers it would be great to know.
