Yeah, I have those in my units, but it will suck as we'll have to do
replacement of systemd-$PACKAGE_VERSION.... or just stick some random
variable there, as sysvinit just check for variable existence but not
actual value.

Anyway, maybe it's better to just ignore it and go straight with
systemd-native actions. Would you mind sharing your ideas about them?
Maybe I can help there as well.
