Recently wanted to try KDE 6 on my second laptop and after being pissed off at the lack of encryption with Void installer (gotta do it manually, have done it in the past but I’m lazy), another fail with NixOs (known bug with encryption in the latest stable installer) the easiest way was installing Arch lol.
I used archinstall as suggested, just answer questions, no manual voodoo incantation required. You can do it.
