I agree.  I never had a problem with init scripts.  Anyone who 
understood bash/sh could fairly easily come to grips with init scripts.  
I have no idea where to look for whatever starts up services with 
systemd.  What language is systemd written in...?  no idea.  Yes, I 
tried reading docs, but they're so vague and inscrutable that I gave 
up.  E.g., what is a "unit"?  Could they have picked a word more vague?  
What does "unit" tell us which "thing" doesn't?  Basically, a service is 
either running or stopped... so what is "static"?  "Static" means the 
opposite of "moving" or "dynamic".  How does "static" describe a service?

In short, although computer geeks generally aren't known for being good 
at documentation, in the commercial world at any rate.  But this is 
GNU/Linux.  We rely on online documentation and the open source 
community to figure out problems and make improvements. Lacking sensible 
documentation, it's hard to figure out problems. If problems can't be 
figured out, we're faced with problematic systems.  And who's going to 
tolerate that for long?  How is that an improvement over Redmondware?
