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.
