Comment (by rjvbertin@…):

 I've been hacking some more at getting privileged DBus helpers to work,
 for instance the one in `port:kf5-libksysguard` that is used to control
 process priority or to send signals to processes running with a different
 UID.

 With the attached patch libdbus will now accept to run setuid, have a
 better chance at finding the session bus socket when run through sudo if
 the following line is added to /etc/sudoers (using `visudo` evidently):

 {{{
 Defaults        env_keep += "DBUS_LAUNCHD_SESSION_BUS_SOCKET"
 }}}

 and privileged workers actually seem to work if the system dbus is running
 and one has used the following magic formula at least once in the current
 login session:

 {{{
 sudo launchctl setenv DBUS_LAUNCHD_SESSION_BUS_SOCKET
 $DBUS_LAUNCHD_SESSION_BUS_SOCKET
 }}}
