from selecting it in error. It has to be used ONLY for debugging init, never in production, as resulting init has serious differences.

When respawn entries are removed from inittab and a SIGHUP is

sent to init, this feature will kill the processes that have

|
been removed.

help
|
|
With nonzero setting, init sends TERM, forks, child waits N
|
|
seconds, sends KILL and exits. Setting it too high is unwise
|
|
(child will hang around for too long and can actually kill
|
|
wrong process!)

help
|
|
If this option is enabled, init will try to give a controlling
|
|
tty to any command which has leading hyphen (often it's "-/bin/sh").
|
|
More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
|
|
If device attached to STDIN_FILENO can be a ctty but is not yet
|
|
a ctty for other session, it will become this process' ctty.
|
|
This is not the traditional init behavour, but is often what you want
|
|
in an embedded system where the console is only accessed during
|
|
development or for maintenance.
|
|
NB: using cttyhack applet may work better.

If this option is enabled and the file /.init_enable_core

core file sizes. If this option is disabled, processes

help
|
|
Legacy support for running init under the old-style initrd. Allows
|
|
the name linuxrc to act as init, and it doesn't assume init is PID 1.
|
|

This does not apply to initramfs, which runs /init as PID 1 and
|
|
requires no special support.
