Sorry, that guide was written for systems running systemd and the install manual you followed was a from an opinionated Arch user for SysVinit.

Oh, this guide is 11 years old written by someone who hated Wayland, so no, modern KDE won’t work with it.

Just use Arch Wiki, it’s the best for beginners, but also don’t install Arch unless you know what you’re doing already because it’s the worst for beginners.

I suspect that LLMs do pretty well with troubleshooting Linux thanks to those manuals and old forum posts. After using them to troubleshoot Linux based devices, I tried the same thing on Windows and it struggled to figure out what commands to run.

Windows is a mess to configure and troubleshoot, even with the help of LLMs. Microsoft could have spent their investment trying to fix that, but I don't think they have.

"Copilot can troubleshoot your computer" could have been a selling point, but they'd have to admit that windows 11 is a buggy mess

Now search for a stack overflow comment, with one answer that's not relevant and doesn't work anymore and 30 "this is a duplicate it's already been answered in a post 10 years ago", and 1 niche forum with someone who had the exact issue, followed with "Thanks I figured it out".

Yeah that's the proper way to do it.

There's a guy at work constantly asking AI everything on his second screen. He came to me after failing to figure out an issue using it. I said "oh yeah let's look at the documentation, I bet there's an example for this exact scenario" and sure enough there was. Made the change, tested and working.

On the other hand, any time I want to do something with Ansible, I start off reading the docs, can't find what I need, scour a bunch of search results, and when that fails somehow AI can produce a working example of what I need in a few tries.

For how to use bash, you can easily resort to local models with LMStudio. No internet search needed.
