Every process has a parent process, with the exception of [init], whose parent process ID (PPID) is 0. It is important to understand the effects of killing a process, especially if that process has spawned child processes.

This doesn't mean such a thing doesn't exist, but my understanding of it is in line with this quote. Interesting topic, though, because if a rootkit could be written to accomplish this "init parent process", then the rootkit would gain complete visibility of the entire system's process space(s).

btwn pid 0 is for scheduler.

Now sysVinit is replaced by the likes of upstart(ubuntu and debian),initng(gentoo?) etc.

Feature Highlights

• Tasks and Services are started and stopped by events
• Events are generated as tasks and services are started and stopped
• Events may be received from any other process on the system
• Services may be respawned if they die unexpectedly
• Bi-directional communication with init daemon to discover which jobs are running, why jobs failed, etc.

Planned Features

• Events generated at timed intervals or scheduled times
• Events generated as files or directories are changed
• Supervision and respawning of daemons which separate from their parent process
• User services, which users can start and stop themselves
• Communication with the init daemon over DBUS

it seems many things are changing...in future no zombie processes left in ur unixen.
