Will my OS break if I make it the system Read Only? I am installing a raspberry pi 4 (Raspberry Pi OS (64-bit)) in my car and read on Lemmy that if I make the system files Read Only my system won’t get corrupt when power is abruptly turned off. I will leave the ‘home’ directory read-write. I realize I will have to remove the drive and run updates regularly.
A better way to do this would be to use the overlay filesystem which will use some of your RAM to hold temporary files written to the partition. When rebooting the system will start over from when you enabled the overlay filesystem.

Looks good! I’ll give it a try. Thanks!!
