13 init is the first program run when the system boots.
20 Turn this on to disable all the dangerous
21 rebooting stuff when debugging.
23 config FEATURE_USE_INITTAB
24 bool "Support reading an inittab file"
28 Allow init to read an inittab file when the system boot.
30 config FEATURE_INIT_SCTTY
31 bool "Support running commands with a controlling-tty"
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.
41 config FEATURE_EXTRA_QUIET
42 bool "Be _extra_ quiet on boot"
46 Prevent init from logging some messages to the console during boot.
48 config FEATURE_INIT_COREDUMPS
49 bool "Support dumping core for child processes (debugging only)"
53 If this option is enabled and the file /.init_enable_core
54 exists, then init will call setrlimit() to allow unlimited
55 core file sizes. If this option is disabled, processes
56 will not generate any core files.
61 bool "Support running init from within an initrd (not initramfs)"
65 Legacy support for running init under the old-style initrd. Allows
66 the name linuxrc to act as init, and it doesn't assume init is PID 1.
68 This does not apply to initramfs, which runs /init as PID 1 and
69 requires no special support.
72 bool "poweroff, halt, and reboot"
75 Stop all processes and either halt, reboot, or power off the system.
81 Mesg controls access to your terminal by others. It is typically
82 used to allow or disallow other users to write to your terminal
