INIT(8) 						      System Manager's Manual							   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 accepting 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 service class.  Otherwise init uses the value of the environment 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 regardless 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.
