   3 NAME
   4      zcons - Zone console device driver
   5 
   6 DESCRIPTION
   7      The zcons character driver exports the console for system zones.  The
   8      driver is fundamentally similar to a pseudo-terminal device, and is thus
   9      comprised of two sides:
  10 
  11      o   a manager device, which applications in the global zone can open for
  12          communication
  13 
  14      o   a subsidiary device, which processes in the non-global zone can write
  15          to, to communicate with global zone management applications
  16 
  17      Applications must not depend on the location of /dev or /devices entries
  18      exposed by zcons in the global zone.  Inside a non-global zone, the zcons
  19      subsidiary device is fronted by /dev/console and other console-related
  20      symbolic links, which are used by applications that expect to write to
  21      the system console.
  22 
  23      The zcons driver is not a Committed interface, and may change at any
  24      time.
