Usually, when people reports this kind of behavior, it is because the
initscript is doing some "ugly" things or is tricking systemd in the way
it is trying to map the initscript to one of the "common" system service
type.

So, my questions would be :
- is your script tries to switch to another user (calling su foobar) to
start a process as a non-root user ?
- is your script tries to spawn a process which might take a long time
before it terminates ?

The best way to debug this would be to boot systemd into debug mode (add
systemd.log_level=debug to your kernel cmdline or use "systemd-analyse
set-log-level debug" to change the debug output for the current
session), then start your initscript, then terminate it (I'm assuming
you have the same issue when stopping it and not only at shutdown).
