When the existing information isn't super helpful, and the problem requires deep understanding of Linux, there are two choices:
-
Find an active Linux forum and ask your question, ignore the assholes telling you to RTFM and wait a few days for someone to ask you to provide the output of a command you never knew existed, go through several rounds of remote asynchronous troubleshooting over a few days and eventually maybe you figure out what's wrong. You are amazing, you make the community amazing, but meanwhile my computer is unstable and I can't use it.
-
Tell AI what symptoms you're experiencing, it gives you basic troubleshooting steps and explains them, and what took days now takes minutes.
Or, a better example, say you know what you want to do: deploy some docker containers including caddy and cloudflared, you want to deploy them through a CI process so it's repeatable, you want to segment their networks. Say you're well versed in all these topics but don't have much docker or compose experience, you can wade through the documentation to figure out the best way to set it up, and it'll take you a few days. Or describe the end state and have a solid starting point and enough explanation to correct bad AI assumptions and skip the first few weeks of regretting a decision because no one highlighted where it could go wrong.
AI makes reading the manual for many integrated systems possible.
