  8. bool "Enable systemd support"
  9. default BUSYBOX_DEFAULT_FEATURE_SYSTEMD
  10. help
  11. If you plan to use busybox daemons on a system where daemons
  12. are controlled by systemd, enable this option.
  13. If you don't use systemd, it is still safe to enable it,
  14. but the downside is increased code size.
  15. config BUSYBOX_CONFIG_FEATURE_RTMINMAX

  17. default BUSYBOX_DEFAULT_FEATURE_RTMINMAX

  47. bool "Support for /etc/networks"
  48. default BUSYBOX_DEFAULT_FEATURE_ETC_NETWORKS

  58. This option allows utilities such as 'more' and 'top' to determine
  59. the size of the screen. If you leave this disabled, your utilities
  60. that display things on the screen will be especially primitive and
  61. will be unable to determine the current screen size, and will be
  62. unable to move the cursor.
  63. config BUSYBOX_CONFIG_FEATURE_EDITING

  73. help
  74. Line editing code uses on-stack buffers for storage.

  76. benefits from smaller stack usage.

  128. help
  129. Allow usage of "ESC [ 6 n" sequence. Terminal answers back with
  130. current cursor position. This information is used to make line
  131. editing more robust in some cases.
  132. If you are not sure whether your terminals respond to this code
  133. correctly, or want to save on code size (about 400 bytes),
  134. then do not turn this option on.
  135. config BUSYBOX_CONFIG_FEATURE_NON_POSIX_CP
  136. bool "Non-POSIX, but safer, copying to special nodes"

  138. help
  139. With this option, "cp file symlink" will delete symlink
  140. and create a regular file. This does not conform to POSIX,
  141. but prevents a symlink attack.
  142. Similarly, "cp file device" will not send file's data
  143. to the device. (To do that, use "cat file >device")
  144. config BUSYBOX_CONFIG_FEATURE_VERBOSE_CP_MESSAGE

  151. $ cp file /vmlinuz/file
  152. cp: cannot stat '/vmlinuz/file': Path has non-directory component

  154. cp: cannot create '/does_not_exist/file': No such file or directory
  155. cp: cannot stat '/vmlinuz/file': Not a directory
  156. This will cost you ~60 bytes.

  168. default BUSYBOX_DEFAULT_FEATURE_SKIP_ROOTFS
  169. help
  170. Ignore rootfs entry in mount table.
  171. In Linux, kernel has a special filesystem, rootfs, which is initially
  172. mounted on /. It contains initramfs data, if kernel is configured
  173. to have one. Usually, another file system is mounted over / early
  174. in boot process, and therefore most tools which manipulate
  175. mount table, such as df, will skip rootfs entry.
  176. However, some systems do not mount anything on /.
  177. If you need to configure busybox for one of these systems,
  178. you may find useful to turn this option off to make df show
  179. initramfs statistic.
  180. Otherwise, choose Y.

  185. help
  186. Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
  187. time intervals (time, ping, traceroute etc need this).
  188. Probably requires Linux 2.6+. If not selected, gettimeofday
  189. will be used instead (which gives wrong results if date/time
  190. is reset).

  195. Use ioctl names rather than hex values in error messages
  196. (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
  197. saves about 1400 bytes.
