A couple years ago they approved a curated script, that’s now bundled with the iso. If you already know your install flow, this won’t really add anything to your experience. I’d still recommend the official way
if you want to use it to judge someones knowledge and ability to use documentation, I‘d ask if they have installed arch, by hand, at least once. Calling using automation cheating is assuming they mean „by hand“ which probably isnt fair.
Curiously I did the same days ago when I ditched Fedora 40 because of problems, my CPU was 90% when opened Super Tux lol so I finally tryed out Arch (btw). Wish me luck
