Relatedly, I made an embedded product. I built a live CD (yes this was a while ago) for my employer with the entire development environment. As long as you can find an x86 machine with CD-ROM you could build, compile, test, and program using the exact environment I did twenty years ago.
Maybe today I'd do micropython on ESP32. Download text file from device, edit, upload back on.
Same. (Flash drive + busybox edition).
There's at least one customer out there who has an RPi with NixOS on it from me. Probably still works to this day. It was the best use of NixOS I think I've ever found.
