10 bool "bootchartd"
11 default n
12 help
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.
17
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.

27 help
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.

100 depends on BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
101 help
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
105 the wrong process!)

107 config BUSYBOX_CONFIG_FEATURE_INIT_SCTTY
108 bool "Run commands with leading dash with controlling tty"
109 default n
110 depends on BUSYBOX_CONFIG_INIT
111 help
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.

139 If this option is enabled and the file /.init_enable_core

148 help
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.
151
152 This does not apply to initramfs, which runs /init as PID 1 and
153 requires no special support.

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.
163
164 Note that on Linux, init attempts to detect serial terminal and
165 sets TERM to "vt102" if one is found.

177 help
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.
181
182 If you set this option to N, "mesg y" will enable writing
183 by anybody at all. This is not recommended.
