     ROOT(3)                                                   ROOT(3)

     NAME
          root - the root file system

     SYNOPSIS
          /
          /chan
          /dev
          /net
          /nvfs
          /prog
          /osinit.dis

     DESCRIPTION
          This device is set up by the kernel to be the initial root
          of the name space.  In the emulation environment, the names
          in the one-level tree shown above are mostly just place-
          holders, to allow a place on which to bind (see sys-
          bind(2)).

          In the native environment, an arbitrary initial directory
          structure and file content can be built-in when the kernel
          is configured, but it will typically include at least the
          names above, to act as mount points.  The required file
          /osinit.dis (not present in the emulation environment) pro-
          vides an executable Dis binary when read, and is the first
          program invoked when initialising the system.  Other files
          needed for bootstrap might also reside in this device.
