Is there such a thing as a 'Live' Raspbian installation. By that I mean that the distro is read from the SD card into RAM and then everything runs from memory.
The reason I would like to use this is that I am currently working on a Project using a Pi Zero to ring the bells in a Model Town Minster. The thing will have to run unattended for long periods (weeks and months) and suffer from uncontrolled shut-downs due to power cuts, operators simply pulling the plug, etc (no monitor or keyboard). A live instance will protect the SD Card from corruption.
Last year, we did something similar using piCore and this has been running successfully since March, but there are a number of reasons why it would be better to do it with Raspbian this time.
Has anyone done it?
