It’s not really a big deal, but I am currently writing this using a linux kernel I compiled from source, which certainly feels like an accomplishment. The Arch Wiki has made the process fairly easy to follow. I just took the stock Arch Linux configuration without changes for now.
The most important part of this is of course that I have the option to do that, to take the source code of this incredible project and build my own kernel binary.
I didn’t dare try to recompile it myself until I saw someone do it in a Youtube video. Changing the config is literally an interactive menu with labelled options and buttons. And your distro almost certainly includes a copy of the settings it uses, so you can just change a few values and keep everything else the same.
