If dbus is build with inotify support on Linux, it will watch 
directories specified as service directory (see 
https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/bus/dir-watch-inotify.c).

If files are changed, a SIGHUP signal is send to the dbus server process 
(https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/bus/dir-watch-inotify.c:74), 
which reloads configuration files (see 
https://gitlab.freedesktop.org/dbus/dbus/-/blob/master/doc/dbus-daemon.1.xml.in#L73)
