So my question is simple, I often flash a couple of different OSes to try in different Rpi's and often don't label the actual SD cards to distinguish then from each other. So days later I end up mixing them up. It's especially kinda hard to write on a microSD card.
I stumbled upon this which offers a few suggestions, but I was wondering if it wasn't possible to just examine the flashed files to determine what OS and version I have in there. For example for an Ubuntu SD card I created, I can clearly see find a
README.diskdefines which tells me.
Is there any default files on a raspbian image-flashed SD card that identifies this?
