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.

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

31 bool "Support killing processes that have been removed from inittab"
32 default n
33 depends on BUSYBOX_CONFIG_FEATURE_USE_INITTAB
34 help
35 When respawn entries are removed from inittab and a SIGHUP is
36 sent to init, this feature will kill the processes that have
37 been removed.

39 config BUSYBOX_CONFIG_FEATURE_KILL_DELAY
40 int "How long to wait between TERM and KILL (0 - send TERM only)" if FEATURE_KILL_REMOVED
41 range 0 1024
42 default 0
43 help
44 With nonzero setting, init sends TERM, forks, child waits N
45 seconds, sends KILL and exits. Setting it too high is unwise
46 (child will hang around for too long and can actually kill
47 wrong process!)

49 config BUSYBOX_CONFIG_FEATURE_INIT_SCTTY
50 bool "Run commands with leading dash with controlling tty"
51 default n
52 depends on BUSYBOX_CONFIG_INIT
53 help
54 If this option is enabled, init will try to give a controlling
55 tty to any command which has leading hyphen (often it's "-/bin/sh").
56 More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
57 If device attached to STDIN_FILENO can be a ctty but is not yet
58 a ctty for other session, it will become this process' ctty.
59 This is not the traditional init behavour, but is often what you want
60 in an embedded system where the console is only accessed during
61 development or for maintenance.
62 NB: using cttyhack applet may work better.

77 bool "Support dumping core for child processes (debugging only)"
78 default n
79 depends on BUSYBOX_CONFIG_INIT
80 help
81 If this option is enabled and the file /.init_enable_core
82 exists, then init will call setrlimit() to allow unlimited
83 core file sizes. If this option is disabled, processes
84 will not generate any core files.

88 config BUSYBOX_CONFIG_FEATURE_INITRD
89 bool "Support running init from within an initrd (not initramfs)"
90 default n
91 depends on BUSYBOX_CONFIG_INIT
92 help
93 Legacy support for running init under the old-style initrd. Allows
94 the name linuxrc to act as init, and it doesn't assume init is PID 1.
95
96 This does not apply to initramfs, which runs /init as PID 1 and
97 requires no special support.
