The init program is the first program run after your kernel begins running. It is configured with the /etc/inittab file. By modifying your /etc/inittab file, you change your system configuration in the following areas:
init.Answer:'init' is always process ID 1.
The Linux kernel will automatically call "init." init will in turn launch any other processes. You can add a process in by creating a script for it in the appropriate run level.
The Linux kernel does not have a process id (also called pid). Process 1 is almost always the process scheduler, init. PIDs are assigned to each subsequent process that is started and they will usually vary. Do not remove init, doing so would likely have catastrophic consequences, a kernel panic for instance. Unless you particularly enjoy using the crash utility. $ man crash [JMH]
init 6
/etc/rc5.bigd.d
There's no single file that contains the boot information. Nor is the method of booting uniform across all platforms and distributions. There are dozens of bootloaders, each of which have their own configuration files in various locations.
The process is called 'init'
Assuming the Linux distribution in question uses a classic SysV Init, you run, as root: # init 2 If you have systemd then there is no runlevel 2. I don't know about upstart. OpenRC is built around SysV Init, but likely systems using it generally ignore runlevels in favor of the initscript configs. Further, most Linux distributions I can think of don't use runlevel 2 at all. Check the documentation for your distribution to see what it is, if anything.
zombie processes are inherited by the 'init' process (PID 1)
Init, short for initialization is a process that is the direct or indirect ancestor of all other processes. It is the first process started during booting. It collects all processes that are have been 'orphaned'. Init runs until the system is powered off.
The Linux kernel doesn't consider itself a process, therefore it has no process id.
Usually any orphaned process is owned by the 'init' process (process #1)
