We need a system that people can install at home, and that never needs someone to configure or maintain it.

We need a system that people can throw on a VPS, and that needs no maintenance or configuration.

If you need a human to manually configure this stuff, it’s broken. The only situation where systemd isn’t useful is when you’re a small company, but large enough to be able to afford an ops guy for every issue there is. Generally, if you need ops to configure the base OS, you’re doing stuff wrong.

This whole point about devops and system is about automating sysadmins away, and this is a very necessary and worthy step.
