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