I think some of the other comments have addressed this, but I'll comment on the rollback issue. If you just want to rollback you can download the current package if it's not in your cache. If you want and rollback to previous version, there's downgrade and the Arch Rollback Machine https://wiki.archlinux.org/index.php/Downgrade#ARM https://wiki.archlinux.org/index.php/Downgrade#ARM Really, though, it's never been an issue for me. I've yet to encounter a situation where I nuke my cache and don't have rollback packages available. It boils down to a management issue. If you are nuking your package cache, I assume you are smart enough to have determined your system is running correctly first. There are cases where you might still want to rollback after clearing your package cache, so there is ARM. Personally, if I ever hit that situation (absolute worst case scenario) I have backups and can reinstall an Arch system in minutes. Haven't had the need yet.
