INIT(8)                                                   INIT(8)

     NAME
          init - initialize machine upon booting

     SYNOPSIS
          /$cputype/init [ -ctm ] [ command ... ]

     DESCRIPTION
          Init initializes the machine: it establishes the name space
          (see namespace(4) and newns in auth(2)), and environment
          (see env(3)) and starts a shell (rc(1)) on the console.  If
          a command is supplied, that is run instead of the shell.  On
          a CPU server the invoked shell runs cpurc(8) before accept-
          ing commands on the console; on a terminal, it runs termrc
          and then the user's profile.  Options -t (terminal) and -c
          (CPU) force the behavior to correspond to the specified ser-
          vice class.  Otherwise init uses the value of the environ-
          ment variable $service to decide the service class.

          Init sets environment variables $service (either to the
          incoming value or according to -t or -c), $objtype (to the
          value of $cputype), $user (to the contents of #c/user), and
          $timezone (to the contents of /adm/timezone/local).

          With option -m init starts only an interactive shell regard-
          less of the command or service class.

          On a CPU server, init requires the machine's password to be
          supplied before starting rc on the console.

          Init is invoked by boot(8), which sets the arguments as
          appropriate.
