INIT(8)
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). 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.
