</div>they did not ported it to systemd, but we don't need them :)<br>

I've tested it on my system, but just once, seems my apc ups is deffective,<br>
because it reports error code with uninteruptable beep (it fails its own<br>
battery test when battery is (almost) empty - after AC reconnected). This is<br>
new ups with new battery, so I'll retest it, but most probably I'll need to<br>
send it back to apc. Anyway, sw part was working fine.<br></blockquote><div><br>if you need a unit, you still have my offer (Eaton), iirc...<br><br></div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
upsmon nor upsd does not support "foreground mode", which is preffered<br>
(see <a href="http://0pointer.de/public/systemd-man/daemon.html" target="_blank">http://0pointer.de/public/systemd-man/daemon.html</a> ) but it's not that big<br>
deal.<br></blockquote><div><br>use '-D' ?!<br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
eh... seems I've forgot other comments... I'll have to write them down next<br>
time :)<br>

</div>just do:<br>
<br>
printf "#!/bin/sh\n upsmon -K >/dev/null 2>&1 && upsdrvctl shutdown" ><br>
/lib/systemd/system-shutdown/upsshutdown<br>
<br>
and prepare for systemd's almighty grumbling :D There was some futile<br>

with systemd's limited possibilities, the only thing I see is the creation of another .service file that Exec it on Stop, and that is executed at the very end of the system shutdown?<br><br>cheers,<br>Arnaud<br>-- <br>
