Discoverability is such a thing. For example, which of these do I want?:

    man systemd.{exec,unit,service}

It's not too bad to get a general feel for what's possible, but recalling where is frustrating. These three are so closely related they're notable. Others, like timers, are a little more obvious.

I've settled on Ansible roles. I define the important bits and config mgmt does the rest
