Yes. If you ask any daemon or group to shutdown, the system shuts
down all its dependents before it shuts down that daemon/group.
(Every startup script takes `start' or `stop' as an argument.)
This means that if you, say, shut down your database, it will make
sure your web server and radius server which depend on that database
are correctly shut down first.
