-Init is the parent of all processes.

-This version of init is designed to be run only by the kernel.

-BusyBox init doesn't support multiple runlevels. The runlevels field of the

- WARNING: This field has a non-traditional meaning for BusyBox init!
- The id field is used by BusyBox init to specify the controlling tty for
- the specified process to run on. The contents of this field are
- appended to "/dev/" and used as-is. There is no need for this field to
- be unique, although if it isn't you may have strange results. If this
- field is left blank, it is completely ignored. Also note that if
- BusyBox detects that a serial console is in use, then all entries
- containing non-empty id fields will _not_ be run. BusyBox init does
- nothing with utmp. We don't need no stinkin' utmp.
