The inittab file is composed of entries that are position-dependent and have the following format:
id:rstate:action:process
The entry fields are:
id A one- to four-character value used to uniquely identify an entry.
rstate defines the run level in which this entry is to be processed. A process can be
assigned to one or more run levels. No entry in this fields means all run level.
action A keyword in this field tells boot init how to treat the process specified in the
process field. Here are some of the actions that can be specified:
boot Process the entry only at boot init's boot-time read of the
inittab file. Boot init starts the process, does not wait for its
termination, and when it dies, does not restart the process.
bootwait Process the entry only at boot init's boot-time read of the
inittab file. Boot init starts the process, waits for its
termination, and, when it dies, does not restart the process.
initdefault the default run level
respawn If the process does not exist, start the process; do not wait for
its termination (continue scanning the inittab file). When it
dies, restart the process. If the process currently exists, do
nothing and continue scanning the inittab file.
process This is the shell command to be executed.
The processes that are started by default are:
ioinitrc, mtinit, dasetup and stty
Initialization of IO subsystem tape devices multiplexer and console respectively.
