idmkinit(1M) UNIX System V(Base System) idmkinit(1M)
NAME
idmkinit - reads files containing specifications
SYNOPSIS
/etc/conf/bin/idmkinit
DESCRIPTION
This command reads the files containing specifications of /etc/inittab
entries from /etc/conf/init.d and constructs a new inittab file in
/etc/conf/cf.d . It returns 0 on success and a positive number on error.
The files in /etc/conf/init.d are copies of the Init modules in device
Driver Software Packages (DSP). There is at most one Init file per DSP.
Each file contains one line for each inittab entry to be installed.
There may be multiple lines (i.e., multiple inittab entries) per file.
An inittab entry has the form (the id field is often called the tag):
id:rstate:action:process
The Init module entry must have one of the following forms:
action:process
rstate:action:process
id:rstate:action:process
When idmkinit encounters an entry of the first type, a valid id field
will be generated, and an rstate field of 2 (indicating run on init
state 2) will be generated. When an entry of the second type is
encountered only the id field is prepended. An entry of the third type
is incorporated into the new inittab unchanged.
Since add-on inittab entries specify init state 2 for their rstate field
most often, an entry of the first type should almost always be used. An
entry of the second type may be specified if you need to specify other
than state 2. DSP's should avoid specifying the id field as in the third
entry, since other add-on applications or DSPs may have already used the
id value you have chosen. The /etc/init program will encounter serious
errors if one or more inittab entries contain the same id field.
idmkinit determines which of the three forms above is being used for the
entry by requiring each entry to have a valid action keyword. Valid
action values are as follows:
off
respawn
ondemand
once
wait
boot
bootwait
powerfail
powerwait

The idmkinit command is called automatically upon entering init State 2
on the next system reboot after a kernel reconfiguration to establish the
correct /etc/inittab for the running /unix kernel. idmkinit can be
called as a user level command to test modification of inittab before a
DSP is actually built. It is also useful in installation scripts that do
not reconfigure the kernel, but need to create inittab entries. In this
case, the inittab generated by idmkinit must be copied to /etc/inittab ,
and a telinit q command must be run to make the new entry take affect.
The command line options are:
-o directory inittab will be created in the directory specified rather
than /etc/conf/cf.d .
-i directory The ID file init.base, which normally resides in
/etc/conf/cf.d, can be found in the directory specified.
-e directory The Init modules that are usually in /etc/conf/init.d can
be found in the directory specified.
-# Print debugging information.
ERROR MESSAGES
An exit value of zero indicates success. If an error was encountered,
idmkinit will exit with a non-zero value and report an error message.
All error messages are designed to be self-explanatory.
