i was toying aroud sd_notify and sd-daemon.h and found this section in
systemd/sd-daemon.h#L234-L235 it said:
Daemons can choose to send additional variables. However, it is recommended
to prefix variable names not listed above with X_.
So naturally i tried
and apparently systemd has no problem with that, but my questions are 2 now:
1) What does systemd do with this information?
2) How can i query this x_answer variable i just gave?
