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.
