  12         help
  13           init is the first program run when the system boots.

  15 config BUSYBOX_CONFIG_DEBUG_INIT
  16         bool "Debugging aid"

  19         help
  20           Turn this on to disable all the dangerous
  21           rebooting stuff when debugging.

  24         bool "Support reading an inittab file"

  27         help
  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.
  38
  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.

  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.

 107         default y
 108         help
 109           Mesg controls access to your terminal by others.  It is typically
 110           used to allow or disallow other users to write to your terminal
