As I’m using Dietpi mainly in headless installations I always try to make my filesystem read-only to protect the system from becoming corrupt after power loss.
Adding an option in dietpi-config to set the filesystem to read-only would be a very nice addition that I think many people can benefit from.
Maybe a separate read-write partition can be created for storing files that should last between sessions.
I would like to 2nd this.
I use dietPi on my RPI as a portable emulator machine to keep the kids from being bored when I visit friends and would love to be able to just kill the power instead of counting on them to properly shut it down.
