9 config BUSYBOX_CONFIG_BOOTCHARTD
13 bootchartd is commonly used to profile the boot process
14 for the purpose of speeding it up. In this case, it is started
15 by the kernel as the init process. This is configured by adding
16 the init=/sbin/bootchartd option to the kernel command line.
18 It can also be used to monitor the resource usage of a specific
19 application or the running system in general. In this case,
20 bootchartd is started interactively by running bootchartd start
21 and stopped using bootchartd stop.
23 config BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_BLOATED_HEADER
24 bool "Compatible, bloated header"
26 depends on BUSYBOX_CONFIG_BOOTCHARTD
28 Create extended header file compatible with "big" bootchartd.
29 "Big" bootchartd is a shell script and it dumps some
30 "convenient" info int the header, such as:
31 title = Boot chart for `hostname` (`date`)
32 system.uname = `uname -srvm`
33 system.release = `cat /etc/DISTRO-release`
34 system.cpu = `grep '^model name' /proc/cpuinfo | head -1` ($cpucount)
35 system.kernel.options = `cat /proc/cmdline`
36 This data is not mandatory for bootchart graph generation,
37 and is considered bloat. Nevertheless, this option
38 makes bootchartd applet to dump a subset of it.
40 config BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_CONFIG_FILE
41 bool "Support bootchartd.conf"
43 depends on BUSYBOX_CONFIG_BOOTCHARTD
45 Enable reading and parsing of $PWD/bootchartd.conf
46 and /etc/bootchartd.conf files.
47 config BUSYBOX_CONFIG_HALT
48 bool "poweroff, halt, and reboot"
51 Stop all processes and either halt, reboot, or power off the system.
53 config BUSYBOX_CONFIG_FEATURE_CALL_TELINIT
54 bool "Call telinit on shutdown and reboot"
56 depends on BUSYBOX_CONFIG_HALT && !BUSYBOX_CONFIG_INIT
58 Call an external program (normally telinit) to facilitate
59 a switch to a proper runlevel.
61 This option is only available if you selected halt and friends,
62 but did not select init.
64 config BUSYBOX_CONFIG_TELINIT_PATH
65 string "Path to telinit executable"
66 default "/sbin/telinit"
67 depends on BUSYBOX_CONFIG_FEATURE_CALL_TELINIT
69 When busybox halt and friends have to call external telinit
70 to facilitate proper shutdown, this path is to be used when
71 locating telinit executable.
72 config BUSYBOX_CONFIG_INIT
75 select BUSYBOX_CONFIG_FEATURE_SYSLOG
78 init is the first program run when the system boots.
80 config BUSYBOX_CONFIG_FEATURE_USE_INITTAB
81 bool "Support reading an inittab file"
83 depends on BUSYBOX_CONFIG_INIT
85 Allow init to read an inittab file when the system boot.
87 config BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
88 bool "Support killing processes that have been removed from inittab"
90 depends on BUSYBOX_CONFIG_FEATURE_USE_INITTAB
92 When respawn entries are removed from inittab and a SIGHUP is
93 sent to init, this option will make init kill the processes
94 that have been removed.
96 config BUSYBOX_CONFIG_FEATURE_KILL_DELAY
97 int "How long to wait between TERM and KILL (0 - send TERM only)" if FEATURE_KILL_REMOVED
100 depends on BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
102 With nonzero setting, init sends TERM, forks, child waits N
103 seconds, sends KILL and exits. Setting it too high is unwise
104 (child will hang around for too long and could actually kill
107 config BUSYBOX_CONFIG_FEATURE_INIT_SCTTY
108 bool "Run commands with leading dash with controlling tty"
110 depends on BUSYBOX_CONFIG_INIT
112 If this option is enabled, init will try to give a controlling
113 tty to any command which has leading hyphen (often it's "-/bin/sh").
114 More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
115 If device attached to STDIN_FILENO can be a ctty but is not yet
116 a ctty for other session, it will become this process' ctty.
117 This is not the traditional init behavour, but is often what you want
118 in an embedded system where the console is only accessed during
119 development or for maintenance.
120 NB: using cttyhack applet may work better.
122 config BUSYBOX_CONFIG_FEATURE_INIT_SYSLOG
123 bool "Enable init to write to syslog"
125 depends on BUSYBOX_CONFIG_INIT
127 config BUSYBOX_CONFIG_FEATURE_EXTRA_QUIET
128 bool "Be _extra_ quiet on boot"
130 depends on BUSYBOX_CONFIG_INIT
132 Prevent init from logging some messages to the console during boot.
134 config BUSYBOX_CONFIG_FEATURE_INIT_COREDUMPS
135 bool "Support dumping core for child processes (debugging only)"
137 depends on BUSYBOX_CONFIG_INIT
139 If this option is enabled and the file /.init_enable_core
140 exists, then init will call setrlimit() to allow unlimited
141 core file sizes. If this option is disabled, processes
142 will not generate any core files.
144 config BUSYBOX_CONFIG_FEATURE_INITRD
145 bool "Support running init from within an initrd (not initramfs)"
147 depends on BUSYBOX_CONFIG_INIT
149 Legacy support for running init under the old-style initrd. Allows
150 the name linuxrc to act as init, and it doesn't assume init is PID 1.
152 This does not apply to initramfs, which runs /init as PID 1 and
153 requires no special support.
155 config BUSYBOX_CONFIG_INIT_TERMINAL_TYPE
156 string "Initial terminal type"
158 depends on BUSYBOX_CONFIG_INIT
160 This is the initial value set by init for the TERM environment
161 variable. This variable is used by programs which make use of
162 extended terminal capabilities.
164 Note that on Linux, init attempts to detect serial terminal and
165 sets TERM to "vt102" if one is found.
166 config BUSYBOX_CONFIG_MESG
170 Mesg controls access to your terminal by others. It is typically
171 used to allow or disallow other users to write to your terminal
173 config BUSYBOX_CONFIG_FEATURE_MESG_ENABLE_ONLY_GROUP
174 bool "Enable writing to tty only by group, not by everybody"
176 depends on BUSYBOX_CONFIG_MESG
178 Usually, ttys are owned by group "tty", and "write" tool is
179 setgid to this group. This way, "mesg y" only needs to enable
180 "write by owning group" bit in tty mode.
182 If you set this option to N, "mesg y" will enable writing
183 by anybody at all. This is not recommended.
