When respawn entries are removed from inittab and a SIGHUP is
|
|
sent to init, this feature will kill the processes that have
|
|
been removed.

config FEATURE_KILL_DELAY

|
|
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!)

config FEATURE_INIT_SCTTY

bool "Run commands with leading dash with controlling tty"

|
default n

|
depends on INIT
|
|
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.

help
|
|
If this option is enabled and the file /.init_enable_core
|

exists, then init will call setrlimit() to allow unlimited
|
|
core file sizes. If this option is disabled, processes
|
|
will not generate any core files.

default y

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.
