ROOT(3) 						     Library Functions Manual							   ROOT(3)

NAME
       root - the root file system

SYNOPSIS
       /
       /boot
       /dev
       /env
       /proc
       /net

DESCRIPTION
       The syntax is illegal, so this device can only be accessed directly by the kernel.

       This  device  is  set up by the kernel to be the root of the name space.  The names in the one-level tree are mostly just place-holders, to
       allow a place to bind(2) to.  The exception is /boot, which provides executable code when read.	The kernel does an exec(2) of  /boot  when
       initializing.
