Raspberry Pi Model B
I still have one of those laying around and while currently unused I came across a few different ways to set it up.
Full OS
The official OS still supports it, so it can be a viable option.
The alternative operating systems I’d like to experiment with are:
- Alpine Linux, likely in disk less mode. See also this guide and this overlay for an headless setup
- NetBSD
- TinyCore Linux
- A system built with Buildroot
Appliance-style deployment
GoKrazy, but I need to identify what to run on it.
Tricks
Reduce vm.swappiness to write less data to the SD card. More details
Use /usr/bin/tvservice –o to disable HDMI. More details
Disable video out. More details
Reduce logging on by configuring rngd
Use write protection in addition to mounting the SD partition as read only.
More tricks to mitigate instability particularly useful the hardware watchdog.
Setting the systemd.volatile=overlay kernel boot parameter turns the root file system into read-only mode and any modification goes to a tmpfs overlay.
