  7. config BUSYBOX_CONFIG_BOOTCHARTD
  8. bool "bootchartd"
  9. default BUSYBOX_DEFAULT_BOOTCHARTD
  10. help
  11. bootchartd is commonly used to profile the boot process
  12. for the purpose of speeding it up. In this case, it is started
  13. by the kernel as the init process. This is configured by adding
  14. the init=/sbin/bootchartd option to the kernel command line.
  15. It can also be used to monitor the resource usage of a specific
  16. application or the running system in general. In this case,
  17. bootchartd is started interactively by running bootchartd start
  18. and stopped using bootchartd stop.
  19. config BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_BLOATED_HEADER
  20. bool "Compatible, bloated header"
  21. default BUSYBOX_DEFAULT_FEATURE_BOOTCHARTD_BLOATED_HEADER
  22. depends on BUSYBOX_CONFIG_BOOTCHARTD
  23. help
  24. Create extended header file compatible with "big" bootchartd.
  25. "Big" bootchartd is a shell script and it dumps some
  26. "convenient" info int the header, such as:
  27. title = Boot chart for `hostname` (`date`)
  28. system.uname = `uname -srvm`
  29. system.release = `cat /etc/DISTRO-release`
  30. system.cpu = `grep '^model name' /proc/cpuinfo | head -1` ($cpucount)
  31. system.kernel.options = `cat /proc/cmdline`
  32. This data is not mandatory for bootchart graph generation,
  33. and is considered bloat. Nevertheless, this option
  34. makes bootchartd applet to dump a subset of it.
  35. config BUSYBOX_CONFIG_FEATURE_BOOTCHARTD_CONFIG_FILE
  36. bool "Support bootchartd.conf"

  41. and /etc/bootchartd.conf files.
  42. config BUSYBOX_CONFIG_HALT
  43. bool "poweroff, halt, and reboot"
  44. default BUSYBOX_DEFAULT_HALT
  45. help
  46. Stop all processes and either halt, reboot, or power off the system.
  47. config BUSYBOX_CONFIG_FEATURE_CALL_TELINIT

  49. default BUSYBOX_DEFAULT_FEATURE_CALL_TELINIT
  50. depends on BUSYBOX_CONFIG_HALT && !BUSYBOX_CONFIG_INIT
  51. help
  52. Call an external program (normally telinit) to facilitate
  53. a switch to a proper runlevel.
  54. This option is only available if you selected halt and friends,
  55. but did not select init.
  56. config BUSYBOX_CONFIG_TELINIT_PATH
  57. string "Path to telinit executable"
  58. default BUSYBOX_DEFAULT_TELINIT_PATH
  59. depends on BUSYBOX_CONFIG_FEATURE_CALL_TELINIT
  60. help
  61. When busybox halt and friends have to call external telinit
  62. to facilitate proper shutdown, this path is to be used when
  63. locating telinit executable.
  64. config BUSYBOX_CONFIG_INIT
  65. bool "init"
  66. default BUSYBOX_DEFAULT_INIT
  67. select BUSYBOX_CONFIG_FEATURE_SYSLOG
  68. help
  69. init is the first program run when the system boots.
  70. config BUSYBOX_CONFIG_LINUXRC
  71. bool "Support running init from within an initrd (not initramfs)"
  72. default BUSYBOX_DEFAULT_LINUXRC
  73. select BUSYBOX_CONFIG_FEATURE_SYSLOG
  74. help
  75. Legacy support for running init under the old-style initrd. Allows
  76. the name linuxrc to act as init, and it doesn't assume init is PID 1.
  77. This does not apply to initramfs, which runs /init as PID 1 and
  78. requires no special support.
  79. config BUSYBOX_CONFIG_FEATURE_USE_INITTAB
  80. bool "Support reading an inittab file"
  81. default BUSYBOX_DEFAULT_FEATURE_USE_INITTAB
  82. depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_LINUXRC
  83. help
  84. Allow init to read an inittab file when the system boot.
  85. config BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
  86. bool "Support killing processes that have been removed from inittab"
  87. default BUSYBOX_DEFAULT_FEATURE_KILL_REMOVED
  88. depends on BUSYBOX_CONFIG_FEATURE_USE_INITTAB
  89. help
  90. When respawn entries are removed from inittab and a SIGHUP is
  91. sent to init, this option will make init kill the processes
  92. that have been removed.
  93. config BUSYBOX_CONFIG_FEATURE_KILL_DELAY

  96. default BUSYBOX_DEFAULT_FEATURE_KILL_DELAY
  97. depends on BUSYBOX_CONFIG_FEATURE_KILL_REMOVED
  98. help
  99. With nonzero setting, init sends TERM, forks, child waits N
  100. seconds, sends KILL and exits. Setting it too high is unwise
  101. (child will hang around for too long and could actually kill
  102. the wrong process!)
  103. config BUSYBOX_CONFIG_FEATURE_INIT_SCTTY
  104. bool "Run commands with leading dash with controlling tty"
  105. default BUSYBOX_DEFAULT_FEATURE_INIT_SCTTY
  106. depends on BUSYBOX_CONFIG_INIT || BUSYBOX_CONFIG_LINUXRC
  107. help
  108. If this option is enabled, init will try to give a controlling
  109. tty to any command which has leading hyphen (often it's "-/bin/sh").
  110. More precisely, init will do "ioctl(STDIN_FILENO, TIOCSCTTY, 0)".
  111. If device attached to STDIN_FILENO can be a ctty but is not yet
  112. a ctty for other session, it will become this process' ctty.
  113. This is not the traditional init behavour, but is often what you want
  114. in an embedded system where the console is only accessed during
  115. development or for maintenance.
  116. NB: using cttyhack applet may work better.

  132. If this option is enabled and the file /.init_enable_core
  133. exists, then init will call setrlimit() to allow unlimited

  140. help
  141. This is the initial value set by init for the TERM environment
  142. variable. This variable is used by programs which make use of
  143. extended terminal capabilities.
  144. Note that on Linux, init attempts to detect serial terminal and
  145. sets TERM to "vt102" if one is found.
  146. config BUSYBOX_CONFIG_FEATURE_INIT_MODIFY_CMDLINE
  147. bool "Modify the command-line to \"init\""
  148. default BUSYBOX_DEFAULT_FEATURE_INIT_MODIFY_CMDLINE

  150. help
  151. When launched as PID 1 and after parsing its arguments, init
  152. wipes all the arguments but argv[0] and rewrites argv[0] to
  153. contain only "init", so that its command-line appears solely as
  154. "init" in tools such as ps.
  155. If this option is set to Y, init will keep its original behavior,
  156. otherwise, all the arguments including argv[0] will be preserved,
  157. be they parsed or ignored by init.
  158. The original command-line used to launch init can then be
  159. retrieved in /proc/1/cmdline on Linux, for example.
  160. config BUSYBOX_CONFIG_MESG

  164. Mesg controls access to your terminal by others. It is typically

  166. config BUSYBOX_CONFIG_FEATURE_MESG_ENABLE_ONLY_GROUP

  170. help
  171. Usually, ttys are owned by group "tty", and "write" tool is
  172. setgid to this group. This way, "mesg y" only needs to enable
  173. "write by owning group" bit in tty mode.
  174. If you set this option to N, "mesg y" will enable writing
  175. by anybody at all. This is not recommended.
