does LSB even have anything to do w/ systemd behavior or have they reinvented

FWIW,

https://www.freedesktop.org/software/systemd/man/systemd.service.html

    Takes a list of exit status definitions that, when returned by the main service process, will be considered successful termination

does that help?
