Idk, but Arch Linux is a bad model, in my experience. I had inherited a system that ran Arch Linux, but hadn't been updated in a while. Imagine my surprise when I needed to update something, and couldn't. A part of the upgrade path (or whatever you want to call it) had been removed. So now I have an Arch Linux system that hasn't been updated for way too long, and we need to consider abandoning the product that runs on that machine, or invest in porting it to some modern environment. It's hidden behind a firewall with access for only 2 IP addresses, so it's unlikely to get hacked, but it's most undesirable.

If you like that model, fine, but don't force it onto the whole world, unless you can commit more resources to it than to Arch Linux, and basically keep all upgrade paths alive forever.
