init is the first program run when the system boots.

- Allow init to read an inittab file when the system boot.

- If this option is enabled and the file /.init_enable_core

help
- Prevent init from logging some messages to the console
- during boot.
+ When respawn entries are removed from inittab and a SIGHUP is
+ sent to init, this feature will kill the processes that have

help
- Stop all processes and halt the system.
+ 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
- Stop all processes and (try to) power off the system.
+ 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.

- Minimal init, based on minit v0.9.1. This is a simple
- init replacement that handles starting/stopping services,
- and service dependencies. See http://www.fefe.de/minit/
- for additional information.

help
- pidfilehack is used by minit to run servers.
+ 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.
