“I’ve been considering installing Arch the traditional way, on my X220, as a way to force myself to improve.”
I use Arch and so does my wife (she has no idea). The wiki is legendary because it is well used (I’ve written a few bits myself). I’ve used Gentoo for quite a while too but you will find compilation times a bit of a bore.
I own an IT company - I am the MD. I use Arch actually! (and so does my wife)
