Hi Stephen, I recently took over maintenance of arpwatch as part of the pkg-security team, sorry for reviving this more than 7 years old bug.
Thanks for reporting the bug regarding the restart functionality and providing a patch. As you probably know (or knew 7 years ago), the restart functionality only works when arpwatch is run as root. I would like to discourage anyone from running arpwatch as root, so I'm not really in favor of implementing nice features that only work when running as root. Instead of merging your patch I propose the following: * we drop the restart functionality altogether; it was introduced in Debian and is not part of upstream, so this would reduce the delta carried by Debian * we change the systemd unit file to restart arpwatch automatically if it exits uncleanly Would you be fine with that? Thank you Lukas
