  20           Trade binary size versus speed for the md5sum algorithm.

  30         bool "Faster /proc scanning code (+100 bytes)"
  31         default y
  32         help
  33           This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
  34           but code size is slightly bigger.
  35
  36 config BUSYBOX_CONFIG_FEATURE_ETC_NETWORKS
  37         bool "Support for /etc/networks"
  38         default n
  39         help
  40           Enable support for network names in /etc/networks. This is
  41           a rarely used feature which allows you to use names
  42           instead of IP/mask pairs in route command.
  43
  44 config BUSYBOX_CONFIG_FEATURE_EDITING
  45         bool "Command line editing"
  46         default y

  48           Enable line editing (mainly for shell command line).

  53         default 512
  54         depends on BUSYBOX_CONFIG_FEATURE_EDITING
  55         help
  56           Line editing code uses on-stack buffers for storage.
  57           You may want to decrease this parameter if your target machine
  58           benefits from smaller stack usage.
  59
  60 config BUSYBOX_CONFIG_FEATURE_EDITING_VI

  62         default n
  63         depends on BUSYBOX_CONFIG_FEATURE_EDITING
  64         help
  65           Enable vi-style line editing.  In shells, this mode can be
  66           turned on and off with "set -o vi" and "set +o vi".

 100         depends on BUSYBOX_CONFIG_FEATURE_EDITING
 101         help
 102           Setting this option allows for prompts to use things like \w and
 103           \$ and escape codes.
 104
 105 config BUSYBOX_CONFIG_FEATURE_VERBOSE_CP_MESSAGE
 106         bool "Give more precise messages when copy fails (cp, mv etc)"

 111             cp: cannot create '/does_not_exist/file': Path does not exist
 112             $ cp file /vmlinuz/file
 113             cp: cannot stat '/vmlinuz/file': Path has non-directory component
 114           If this feature is not enabled, they will be, respectively:
 115             cp: cannot remove '/does_not_exist/file': No such file or directory
 116             cp: cannot stat '/vmlinuz/file': Not a directory
 117           respectively.
 118           This will cost you ~60 bytes.

 125           Size of buffer used by cp, mv, install etc.
 126           Buffers which are 4 kb or less will be allocated on stack.
 127           Bigger buffers will be allocated with mmap, with fallback to 4 kb
 128           stack buffer if mmap fails.

 130 config BUSYBOX_CONFIG_MONOTONIC_SYSCALL
 131         bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"

 134           Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
 135           time intervals (time, ping, traceroute etc need this).
 136           Probably requires Linux 2.6+. If not selected, gettimeofday
 137           will be used instead (which gives wrong results if date/time
 138           is reset).
 139
 140 config BUSYBOX_CONFIG_IOCTL_HEX2STR_ERROR
 141         bool "Use ioctl names rather than hex values in error messages"
 142         default y
 143         help
 144           Use ioctl names rather than hex values in error messages
 145           (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
 146           saves about 1400 bytes.
 147

 153           network applets.
