archinstall?
Back in my day, we needed to do all of that by hand, and there wasn’t even arch-chroot, no, we had to bind mount dev, proc and and sys manually as well!
Though in fairness, before that, there was the AIF, which I also used, but that doesn’t sound so manly.








Almost, as I said,
arch-chrootdidn’t exist back then, and while the official method is still manual,archinstallis part of the official ISO, while back then, no helper was provided, so you had to do it manually.
