I understand the arguments for the move to systemd - and I also understand the 
points of those arguments.  Like most arguments, there are some valid and 
positive points and some not so.

There are times - such as the encompassing of the name resolver code - where 
it just seems a case of replacing old, mature code with new untested code for 
no reason.

Either way, I now have to manage both traditional and systemd based systems. 
Okay, it just means learning new toolsets, but it's something else I have to 
learn, and something else I have to cope with for my bespoke systems and
