Is the “Data Partition” (seen in this diagram) read-only and copy-on-write to RAM when the container is running?
I don’t want my containers (when started) to write anything to SD card. I’m using Raspberry pi 4 with 4GB of memory, there should be plenty of space for everything to be kept in memory.
Ideally only time the balenaOS should write to SD card is when I deploy a new image.
I have a Electron kiosk running in a single container, and I’m worried that the cache directories it creates are written to disk. I know how notorious the Chromium is with IO, it is by far the most IO heavy program with it’s cache, even in Windows 10.
