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

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

  25         depends on BUSYBOX_CONFIG_FEATURE_USE_INITTAB
  26         help
  27           When respawn entries are removed from inittab and a SIGHUP is
  28           sent to init, this feature will kill the processes that have
  29           been removed.

  31 config BUSYBOX_CONFIG_FEATURE_KILL_DELAY
  32         int "How long to wait between TERM and KILL (0 - send TERM only)" if FEATURE_KILL_REMOVED
  33         range 0 1024
  34         default 0
  35         depends on BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
  36         help
  37           With nonzero setting, init sends TERM, forks, child waits N
  38           seconds, sends KILL and exits. Setting it too high is unwise
  39           (child will hang around for too long and could actually kill
  40           the wrong process!)
  41
  42 config BUSYBOX_CONFIG_FEATURE_INIT_SCTTY
  43         bool "Run commands with leading dash with controlling tty"
  44         default n
  45         depends on BUSYBOX_CONFIG_INIT
  46         help
  47           If this option is enabled, init will try to give a controlling
  48           tty to any command which has leading hyphen (often it's "-/bin/sh").
  49           More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
  50           If device attached to STDIN_FILENO can be a ctty but is not yet
  51           a ctty for other session, it will become this process' ctty.
  52           This is not the traditional init behavour, but is often what you want
  53           in an embedded system where the console is only accessed during
  54           development or for maintenance.
  55           NB: using cttyhack applet may work better.

  73         help
  74           If this option is enabled and the file /.init_enable_core
  75           exists, then init will call setrlimit() to allow unlimited
  76           core file sizes. If this option is disabled, processes
  77           will not generate any core files.
  78
  79 config BUSYBOX_CONFIG_FEATURE_INITRD
  80         bool "Support running init from within an initrd (not initramfs)"
  81         default n
  82         depends on BUSYBOX_CONFIG_INIT
  83         help
  84           Legacy support for running init under the old-style initrd. Allows
  85           the name linuxrc to act as init, and it doesn't assume init is PID 1.
  86
  87           This does not apply to initramfs, which runs /init as PID 1 and
  88           requires no special support.

 101           Call an external program (normally telinit) to facilitate
 102           a switch to a proper runlevel.
 103
 104           This option is only available if you selected halt and friends,
 105           but did not select init.

 112           When busybox halt and friends have to call external telinit
 113           to facilitate proper shutdown, this path is to be used when
 114           locating telinit executable.

 119         help
