Arch Linux is an eternal OS, it can migrate through different hardware and there are people who never reinstall it (you don’t need to) for, say, a decade. Mine is half a decade at least, and went through three laptops. The last one was (Intel) MacBook Pro dying on me (the keys), and I just rsynced my system onto another MacBook (booted with Arch install) via ssh. Took me an hour or two in the background. I left my home and returned to a working laptop that needed a few tiny changes in configs here and there.
