I fully agree. That's why I've invested lots of work into my digital signage os (https://info-beamer.com/hosted https://info-beamer.com/hosted): It's booting into a read-only squashfs that contains everything. The squashfs, kernel and PI firmware itself are on the read-only FAT partition. All data that is required as display content ends up on a second read/write partition. If there is any data corruption or similar problem, my system can fully restore that automatically. Here's a small blog post were I wrote about this: https://info-beamer.com/blog/building-a-reliable-raspberry-pi-distribution https://info-beamer.com/blog/building-a-reliable-raspberry-p.... So far the system has never had any problem from power loss or cutting power. Interesting hardware hack you linked there. I haven't seen that one before. Thanks.
