Pure arch is fine, don’t let internet idiots scare you. Just archinstall it, you don’t have to do a manual install. I reckon have a crack at a manual install for learning purposes if your curious.
I had a look at cachy in a VM it seems very similar to me. I used that Shelly gui thing I kind of like it but every now and then I like to manually install the vulnerabilities directly from AUR and npm.











Is that just cause you don’t know how to close it?
