If I’m working for someone else (company or otherwise), I’ll write comments and docs in whatever language I can speak that they want me to (which pretty much means I write comments in English, because I rarely work for Hungarian companies nowadays, and even the ones I did work for preferred English, and these are the only two human languages I can write :().
When working on my own projects, it is always English, because Hungarian doesn’t have good translations for many of the technical terms, so half my comments would be English borrowed words anyway. Might aswell write the rest in English too. Also makes it easier for others to chime in, because there are a whole lot more people speaking English than Hungarian.
It was harder in the beginning, when my command of the English language was far worse, but even then, half-Hungarian/Half-English comments just looked weird, and more jarring than full English, even if that English was kinda bad.
I think the first thing to figure out would be why udev is getting shut down. Perhaps you could extract its logs?
journalctl -b -u systemd-udevd.service
should do the trick. This gets you the logs of the current boot’s udevd service.Once you know why it is shutting down, it will be time to figure out how to stop it from shutting down. That should, hopefully, fix the problem you’re having.
