[arch-general] In the systemd scheme, where should startup/stop scripts for things systemd can't handle go?

also note that you likely want to simply run the service differently
that you had previously.

for example, i modify several .service files -- even ones that are
shipped upstream -- because they are pointlessly configured as
`forking` when they could be much better integrated (ddclient, dhcpd,
hostapd, SEVERAL unfortunately) ...

eg, in general, PID files are not needed anymore, and logs should go
to STDOUT.  so ... set the daemon to FOREGROUND, and DON'T redirect
output (see man systemd.exec for stdout/err options, among others).

... then you can just:

ExecStop=-/bin/kill $MAINPID

.. and be done with it :-)

part of succeeding with systemd is recognizing that 3/4 of the @#$%
-required- before is not only -unnecessary-, but now a hindrance!

other notes from your pasted unit file:
 - Exec* requires absolute paths to binaries
 - $JAVA_OPTS is different from ${JAVA_OPTS}; the former is subjected
to word-splitting while the latter is not (see man bash)
