Considering the running battles I've been having with the middleware teams over 
getting their init scripts right (so the stuff starts at the right time and 
shuts down when it should), I think systemd will be a help.

It's got a learning curve though, definitely.

It may simply be learning curve.
But that is a real effect, so some push-back should be expected and planned for.
(I like to create game changes as much as anyone, so not saying I'm personally 
any better than Poettering and Sievers on the disruption
front.)

Having been slapped down for whining about it (by friends who *like* the new 
MO), I gave it more thought.

The objection is over a certain loss of simplicity.  (There are other features 
creeping into Linux where loss of simplicity is observed.) Frankly, 'systemd' 
is overkill on some points.  For one thing, startup is not a desired state on 
systems where systemd improves startup.
Another is restart: as a community had been getting more compliance on 
consistent PID file use.  But with 'systemd' I can no longer reliably cat the 
PID file to kill the daemon.  I should stop here lest this group also accuse me 
of whining.

The fact that it breaks previous compatibility with Solaris and AIX is
*not* a plus.  I know David and his team do a lot of work with those systems.
