.TH INIT 8
.SH NAME
init: emuinit, osinit \- Inferno initialisation
.SH SYNOPSIS
.EX
Init: module
{
init: fn();
};
.EE
.PP
.B /dis/emuinit.dis
.PP
.B #/./osinit.dis
.SH DESCRIPTION
Both
.IR emu (1)
and the native kernels run a Dis program to initialise the system.
.PP
.I Emuinit
is the default initialisation
program for
.IR emu (1).
.I Emu
sets the environment variable
(see
.IR env (3))
.B /env/emuargs
to the command line originally given to
.IR emu ,
which has the following form:
.IP
.B emu
.RB [ \-d ]
[
.I command
.RI [ " arg ..." ]
]
.PP
.I Emuinit
uses the value of
.B emuargs
to decide which command to start and its arguments.
The default
.I command
is
.BR /dis/sh.dis ,
unless the
.B \-d
option is given, in which case
.B /dis/lib/srv.dis
is used by default instead, to cause
.I emu
to run on the host system as a server (`daemon' mode).
.PP
.I Osinit
is built-in to the
.IR root (3)
of native kernels.
Although the kernel uses the fixed name
.B #/./osinit.dis
the contents are taken from one of the files in
.B /os/init
selected by the
.B init
section of the kernel configuration file.
.IR Osinit 's
action is platform-specific in detail, but might include:
building an initial
.B /dev
by mounting device drivers;
binding the physical network driver (eg,
.IR ether (3))
into
.B /net
and initialising
.IR ip (3),
usually setting addresses and routes using
.BR bootp ;
attaching to a remote file system;
setting up flash translation using
.IR ftl (3);
starting
.I dossrv
or
.I 9660srv
(see
.IR dossrv (4)),
or
.IR kfs (3)
to serve local files from disk or flash memory.
