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.
