    9     bool "init"

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

    15     config FEATURE_USE_INITTAB
    16     bool "Support reading an inittab file"
    17     default y
    18     depends on INIT
    19     help
    20     Allow init to read an inittab file when the system boot.

    22 niro 816 config FEATURE_KILL_REMOVED
    23     bool "Support killing processes that have been removed from inittab"
    24     default y
    25     depends on 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.
    30    
    31     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     help
    36     With nonzero setting, init sends TERM, forks, child waits N
    37     seconds, sends KILL and exits. Setting it too high is unwise
    38     (child will hang around for too long and can actually kill
    39     wrong process!)

    41 niro 532 config FEATURE_INIT_SCTTY
    42 niro 816 bool "Run commands with leading dash with controlling tty"
    43 niro 532 default n
    44     depends on INIT
    45     help
    46 niro 816 If this option is enabled, init will try to give a controlling
    47     tty to any command which has leading hyphen (often it's "-/bin/sh").
    48     More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
    49     If device attached to STDIN_FILENO can be a ctty but is not yet
    50     a ctty for other session, it will become this process' ctty.
    51     This is not the traditional init behavour, but is often what you want
    52     in an embedded system where the console is only accessed during
    53     development or for maintenance.
    54     NB: using cttyhack applet may work better.

    69     bool "Support dumping core for child processes (debugging only)"
    70     default n
    71     depends on INIT
    72     help
    73     If this option is enabled and the file /.init_enable_core
    74     exists, then init will call setrlimit() to allow unlimited
    75 niro 816 core file sizes. If this option is disabled, processes
    76 niro 532 will not generate any core files.
    77    
    78     config FEATURE_INITRD
    79     bool "Support running init from within an initrd (not initramfs)"
    80     default y
    81     depends on INIT
    82     help
    83 niro 816 Legacy support for running init under the old-style initrd. Allows
    84 niro 532 the name linuxrc to act as init, and it doesn't assume init is PID 1.
    85    
    86     This does not apply to initramfs, which runs /init as PID 1 and
    87     requires no special support.
    88    
    89     config HALT
    90     bool "poweroff, halt, and reboot"
    91 niro 816 default n
    92 niro 532 help
    93     Stop all processes and either halt, reboot, or power off the system.
