Arch had a perfectly serviceable installer way back in the day. I used it regularly maybe 15-ish years ago. It was removed. I'm very glad to see another one pop up.

Are we sure this isn't an April fools? I like the idea of having a guided install in addition to the standard one, but it doesn't seem quite in the spirit of the Arch Way.

Apparently not, there's a proper github repo for it that does not date from April 1st!

Ah yes, you are right. Looks like it's scriptable as well. This looks pretty great then, especially having it baked into the installation image.
