8 | config INIT |
9 | bool "init" |
10 | default n |
11 | select FEATURE_SYSLOG |
12 | help |
13 | init is the first program run when the system boots. |
14 | |
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. |
21 | |
22 | 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 | depends on 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 FEATURE_INIT_SCTTY |
43 | bool "Run commands with leading dash with controlling tty" |
44 | default n |
45 | depends on 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. |
56 | |
57 | config FEATURE_INIT_SYSLOG |
58 | bool "Enable init to write to syslog" |
59 | default n |
60 | depends on INIT |
61 | |
62 | config FEATURE_EXTRA_QUIET |
63 | bool "Be _extra_ quiet on boot" |
64 | default y |
65 | depends on INIT |
66 | help |
67 | Prevent init from logging some messages to the console during boot. |
68 | |
69 | config FEATURE_INIT_COREDUMPS |
70 | bool "Support dumping core for child processes (debugging only)" |
71 | default n |
72 | depends on INIT |
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 FEATURE_INITRD |
80 | bool "Support running init from within an initrd (not initramfs)" |
81 | default y |
82 | depends on 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. |
89 | |
90 | config HALT |
91 | bool "poweroff, halt, and reboot" |
92 | default n |
93 | help |
94 | Stop all processes and either halt, reboot, or power off the system. |
95 | |
96 | config FEATURE_CALL_TELINIT |
97 | bool "Call telinit on shutdown and reboot" |
98 | default n |
99 | depends on HALT && !INIT |
100 | help |
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. |
106 | |
107 | config TELINIT_PATH |
108 | string "Path to telinit executable" |
109 | default "/sbin/telinit" |
110 | depends on FEATURE_CALL_TELINIT |
111 | help |
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. |
115 | |
116 | config MESG |
117 | bool "mesg" |
118 | default n |
119 | help |
120 | Mesg controls access to your terminal by others. It is typically |
121 | used to allow or disallow other users to write to your terminal |
122 | |
