8config INIT
9	bool "init"
10	default n
11	select FEATURE_SYSLOG
12	help
13	  init is the first program run when the system boots.
14
15config DEBUG_INIT
16	bool "debugging aid"
17	default n
18	depends on INIT
19	help
20	  Turn this on to disable all the dangerous
21	  rebooting stuff when debugging.
22
23config FEATURE_USE_INITTAB
24	bool "Support reading an inittab file"
25	default y
26	depends on INIT
27	help
28	  Allow init to read an inittab file when the system boot.
29
30config FEATURE_INIT_SCTTY
31	bool "Support running commands with a controlling-tty"
32	default n
33	depends on INIT
34	help
35	  If this option is enabled a command starting with hyphen (-)
36	  is run in its own session (setsid(2)) and possibly with a
37	  controlling tty (TIOCSCTTY).  This is not the traditional init
38	  behavour, but is often what you want in an embedded system where
39	  the console is only accessed during development or for maintenance.
40
41config FEATURE_INIT_SYSLOG
42	bool "Enable init to write to syslog"
43	default n
44	depends on INIT
45
46config FEATURE_EXTRA_QUIET
47	bool "Be _extra_ quiet on boot"
48	default y
49	depends on INIT
50	help
51	  Prevent init from logging some messages to the console during boot.

53config FEATURE_INIT_COREDUMPS
54	bool "Support dumping core for child processes (debugging only)"
55	default n
56	depends on INIT
57	help
58	  If this option is enabled and the file /.init_enable_core
59	  exists, then init will call setrlimit() to allow unlimited
60	  core file sizes.  If this option is disabled, processes
61	  will not generate any core files.

65config FEATURE_INITRD
66	bool "Support running init from within an initrd (not initramfs)"
67	default y
68	depends on INIT
69	help
70	  Legacy support for running init under the old-style initrd.  Allows
71	  the name linuxrc to act as init, and it doesn't assume init is PID 1.
72
73	  This does not apply to initramfs, which runs /init as PID 1 and
74	  requires no special support.
75
76config HALT
77	bool "poweroff, halt, and reboot"
78	default y
79	help
80	  Stop all processes and either halt, reboot, or power off the system.

84	default y
85	help

87	  used to allow or disallow other users to write to your terminal
