+config BUSYBOX_CONFIG_FEATURE_SYSTEMD
+ bool "Enable systemd support"
+ default n
+ help
+ If you plan to use busybox daemons on a system where daemons
+ are controlled by systemd, enable this option.
+ If you don't use systemd, it is still safe to enable it,
+ but the downside is increased code size.
+config BUSYBOX_CONFIG_FEATURE_RTMINMAX
+ bool "Support RTMIN[+n] and RTMAX[-n] signal names"
+ default n
+ help
+ Support RTMIN[+n] and RTMAX[-n] signal names
+ in kill, killall etc. This costs ~250 bytes.

config BUSYBOX_CONFIG_PASSWORD_MINLEN
int "Minimum password length"
default 6
Minimum allowable password length.
config BUSYBOX_CONFIG_MD5_SIZE_VS_SPEED
- int "MD5: Trade Bytes for Speed"
+ int "MD5: Trade bytes for speed (0:fast, 3:slow)"
default 2
range 0 3
help
a rarely used feature which allows you to use names
instead of IP/mask pairs in route command.
+config BUSYBOX_CONFIG_FEATURE_USE_TERMIOS
+ bool "Use termios to manipulate the screen"
+ default n
+ depends on BUSYBOX_CONFIG_MORE || BUSYBOX_CONFIG_TOP || BUSYBOX_CONFIG_POWERTOP
+ help
+ This option allows utilities such as 'more' and 'top' to determine
+ the size of the screen. If you leave this disabled, your utilities
+ that display things on the screen will be especially primitive and
+ will be unable to determine the current screen size, and will be
+ unable to move the cursor.

config BUSYBOX_CONFIG_FEATURE_EDITING
bool "Command line editing"
default y
config BUSYBOX_CONFIG_FEATURE_EDITING_HISTORY
int "History size"
- range 0 99999
+ # Don't allow way too big values here, code uses fixed "char *history[N]" struct member
+ range 0 9999
default 256
depends on BUSYBOX_CONFIG_FEATURE_EDITING

- Specify command history size.
+ Specify command history size (0 - disable).
config BUSYBOX_CONFIG_FEATURE_EDITING_SAVEHISTORY
bool "History saving"

- Enable history saving in ash shell.
+ Enable readline-like Ctrl-R combination for reverse history search.
+ Increases code by about 0.5k.
config BUSYBOX_CONFIG_FEATURE_TAB_COMPLETION
bool "Tab completion"
Setting this option allows for prompts to use things like \w and
\$ and escape codes.
+config BUSYBOX_CONFIG_FEATURE_EDITING_ASK_TERMINAL
+ bool "Query cursor position from terminal"
+ default n
+ depends on BUSYBOX_CONFIG_FEATURE_EDITING
+ help
+ Allow usage of "ESC [ 6 n" sequence. Terminal answers back with
+ current cursor position. This information is used to make line
+ editing more robust in some cases.
+ If you are not sure whether your terminals respond to this code
+ correctly, or want to save on code size (about 400 bytes),
+ then do not turn this option on.
+
+config BUSYBOX_CONFIG_FEATURE_NON_POSIX_CP
+ bool "Non-POSIX, but safer, copying to special nodes"
+ default y
+ help
+ With this option, "cp file symlink" will delete symlink
+ and create a regular file. This does not conform to POSIX,
+ but prevents a symlink attack.
+ Similarly, "cp file device" will not send file's data
+ to the device. (To do that, use "cat file >device")
+
config BUSYBOX_CONFIG_FEATURE_VERBOSE_CP_MESSAGE
bool "Give more precise messages when copy fails (cp, mv etc)"
default n
$ cp file /vmlinuz/file
cp: cannot stat '/vmlinuz/file': Path has non-directory component
If this feature is not enabled, they will be, respectively:
- cp: cannot remove '/does_not_exist/file': No such file or directory
+ cp: cannot create '/does_not_exist/file': No such file or directory
cp: cannot stat '/vmlinuz/file': Not a directory
- respectively.
This will cost you ~60 bytes.

default 4
help
- Size of buffer used by cp, mv, install etc.
+ Size of buffer used by cp, mv, install, wget etc.
Buffers which are 4 kb or less will be allocated on stack.
Bigger buffers will be allocated with mmap, with fallback to 4 kb
stack buffer if mmap fails.
+config BUSYBOX_CONFIG_FEATURE_SKIP_ROOTFS
+ bool "Skip rootfs in mount table"
+ default n
+ help
+ Ignore rootfs entry in mount table.
+
+ In Linux, kernel has a special filesystem, rootfs, which is initially
+ mounted on /. It contains initramfs data, if kernel is configured
+ to have one. Usually, another file system is mounted over / early
+ in boot process, and therefore most tools which manipulate
+ mount table, such as df, will skip rootfs entry.
+
+ However, some systems do not mount anything on /.
+ If you need to configure busybox for one of these systems,
+ you may find useful to turn this option off to make df show
+ initramfs statistic.
+
+ Otherwise, choose Y.
+
config BUSYBOX_CONFIG_MONOTONIC_SYSCALL
bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
default n

help
Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
time intervals (time, ping, traceroute etc need this).
help

network applets.
