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 initialise the system.

­Emuinit is the default initialisation program for emu(1); it reads from ­/dev/emuargs (see cons(3)) the command line arguments given to emu, expected to be of the following form:

­emu [−d] [ ­command [ arg ...] ]

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.

BUGS

The arguments could be given to ­emuinit directly, rather than fussing about with /dev/emuargs.
