.TH INIT 8
.SH NAME
init \- initialize machine upon booting
.SH SYNOPSIS
.B /$cputype/init
[
.B -ctm
] [
.I command ...
]
.SH DESCRIPTION
.I Init
initializes the machine: it establishes the name space (see
.IR namespace (4)
and
.I newns
in
.IR auth (2)),
and environment (see
.IR env (3))
and starts a shell 
.RI ( rc (1))
on the console.
If a
.I command
is supplied, that is run instead of the shell.
On a CPU server the invoked shell runs
.IR cpurc (8)
before accepting commands on the console;
on a terminal, it runs
.IR termrc
and then the user's profile.
Options
.B -t
(terminal)
and
.B -c
(CPU)
force the behavior to correspond to the specified service class.
Otherwise
.I init
uses the value of the environment variable
.B $service
to decide the service class.
.PP
.I Init
sets environment variables
.B $service
(either to the incoming value or according to
.B -t
or
.BR -c ),
.B $objtype
(to the value of
.BR $cputype ),
.B $user
(to the contents of
.BR #c/user ),
and
.B $timezone
(to the contents of
.BR /adm/timezone/local ).
.PP
With option
.B -m
.I init
starts only an interactive shell
regardless of the
.I command
or service class.
.PP
On a CPU server,
.I init
requires the machine's password to be supplied before starting
.I rc
on the console.
.PP
.I Init
is invoked by
.IR boot (8),
which sets the arguments as appropriate.
