Dear Mentors, I'm working on a article about systemd, so i read the following link at first: http://0pointer.de/blog/projects/systemd.html
I found the following context in the above link: /************************************************ Hardware and Software Change Dynamically Modern systems (especially general purpose OS) are highly dynamic in their configuration and use: they are mobile, different applications are started and stopped, different hardware added and removed again. An init system that is responsible for maintaining services needs to listen to hardware and software changes. It needs to dynamically start (and sometimes stop) services as they are needed to run a program or enable some hardware. Most current systems that try to parallelize boot-up still synchronize the start-up of the various daemons involved: since Avahi needs D-Bus, D-Bus is started first, and only when D-Bus signals that it is ready, Avahi is started too. Similar for other services: livirtd and X11 need HAL (well, I am considering the Fedora 13 services here, ignore that HAL is obsolete), hence HAL is started first, before livirtd and X11 are started. And libvirtd also needs Avahi, so it waits for Avahi too. And all of them require syslog, so they all wait until Syslog is fully started up and initialized. And so on. **********************************************************************/ My question is : How it implemented in sysv?
