I have created a persistent Ubuntu Mate USB flash drive using mkusb and configured it to how I want it. I now want to stop anyone from being able to modify it.
I don't mind if the solution is to stop all modification by the user or whether it allows the user to modify just for that session but reverts on reboot.
There is no system login and I would like it to stay that way, but there would need to be some way for me to still gain privileged access for maintenance.
I would like the user to have the exact same desktop as I have setup, i.e. including the shortcuts to network drives.
I would appreciate any suggestions. I would consider myself as beginner to intermediate user, so a little detail may be required.
