I have created a simple kiosk-style Arch Linux installation on a Raspberry Pi that simply launches a web browser and shows some weather information.
To make the daily system bootup/shutdown routine as easy as possible, I mounted all partitions as read-only. This way, the system can be booted by switching on the power and shutdown by simply killing the power (no
sudo shutdown -h now required). Also I created a few special tmpfs partitions for parts of the system that need to be read-write. The system does not have any swap partition.
My concern now is, does this still wear out the SD card? In theory there should be no write-operations going on on the card, but could something else wear it out?
