A write was detected to one of the directories containing D-Bus configuration
files, triggering a configuration reload.

This functionality exists for backwards compatibility to pick up changes to
D-Bus configuration without an explicit reolad request. Typically when
installing or removing third-party software causes D-Bus configuration files
to be added or removed.

It is worth noting that this may cause partial configuration to be loaded in
case dispatching this notification races with the writing of the configuration
files. However, a future notification will then cause the configuration to be
reladed again.
