+config PASSWORD_MINLEN
+        int "Minimum password length"
+        default 6
+        range 5 32
+        help
+          Minimum allowable password length.

+config MD5_SIZE_VS_SPEED
+        int "MD5: Trade bytes for speed (0:fast, 3:slow)"
+        default 2
+        range 0 3
+        help
+          Trade binary size versus speed for the md5sum algorithm.
+          Approximate values running uClibc and hashing
+          linux-2.4.4.tar.bz2 were:
+                            user times (sec)  text size (386)
+          0 (fastest)         1.1                6144

+config FEATURE_FAST_TOP
+        bool "Faster /proc scanning code (+100 bytes)"
+        default n
+        help
+          This option makes top (and ps) ~20% faster (or 20% less CPU hungry),
+          but code size is slightly bigger.
+
+config FEATURE_ETC_NETWORKS
+        bool "Support for /etc/networks"
+        default n
+        help
+          Enable support for network names in /etc/networks. This is
+          a rarely used feature which allows you to use names
+          instead of IP/mask pairs in route command.
+
+config FEATURE_EDITING
+        bool "Command line editing"
+        default n
+        help
+          Enable line editing (mainly for shell command line).
+
+config FEATURE_EDITING_MAX_LEN
+        int "Maximum length of input"
+        range 128 8192
+        default 1024
+        depends on FEATURE_EDITING
+        help
+          Line editing code uses on-stack buffers for storage.
+          You may want to decrease this parameter if your target machine
+          benefits from smaller stack usage.
+
+config FEATURE_EDITING_VI
+        bool "vi-style line editing commands"
+        default n
+        depends on FEATURE_EDITING
+        help
+          Enable vi-style line editing. In shells, this mode can be
+          turned on and off with "set -o vi" and "set +o vi".
+
+config FEATURE_EDITING_HISTORY
+        int "History size"
+        range 0 99999
+        default 15
+        depends on FEATURE_EDITING
+        help
+          Specify command history size.
+
+config FEATURE_EDITING_SAVEHISTORY
+        bool "History saving"
+        default n
+        depends on ASH && FEATURE_EDITING
+        help
+          Enable history saving in ash shell.
+
+config FEATURE_TAB_COMPLETION
+        bool "Tab completion"
+        default n
+        depends on FEATURE_EDITING
+        help
+          Enable tab completion.
+
+config FEATURE_USERNAME_COMPLETION
+        bool "Username completion"
+        default n
+        depends on FEATURE_TAB_COMPLETION
+        help
+          Enable username completion.
+
+config FEATURE_EDITING_FANCY_PROMPT
+        bool "Fancy shell prompts"
+        default n
+        depends on FEATURE_EDITING
+        help
+          Setting this option allows for prompts to use things like \w and
+          \$ and escape codes.
+
+config FEATURE_EDITING_ASK_TERMINAL
+        bool "Query cursor position from terminal"
+        default n
+        depends on 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 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.
+
+config FEATURE_VERBOSE_CP_MESSAGE
+        bool "Give more precise messages when copy fails (cp, mv etc)"
+        default n
+        help
+          Error messages with this feature enabled:
+            $ cp file /does_not_exist/file
+            cp: cannot create '/does_not_exist/file': Path does not exist
+            $ 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 create '/does_not_exist/file': No such file or directory
+            cp: cannot stat '/vmlinuz/file': Not a directory
+          This will cost you ~60 bytes.
+
+config FEATURE_COPYBUF_KB
+        int "Copy buffer size, in kilobytes"
+        range 1 1024
+        default 4
+        help
+          Size of buffer used by cp, mv, install 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 MONOTONIC_SYSCALL
+        bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
+        default y
+        help
+          Use clock_gettime(CLOCK_MONOTONIC) syscall for measuring
+          time intervals (time, ping, traceroute etc need this).
+          Probably requires Linux 2.6+. If not selected, gettimeofday
+          will be used instead (which gives wrong results if date/time
+          is reset).
+
+config IOCTL_HEX2STR_ERROR
+        bool "Use ioctl names rather than hex values in error messages"
+        default y
+        help
+          Use ioctl names rather than hex values in error messages
+          (e.g. VT_DISALLOCATE rather than 0x5608). If disabled this
+          saves about 1400 bytes.
+
+config FEATURE_HWIB
+        bool "Support infiniband HW"
+        default y
+        help
+          Support for printing infiniband addresses in
+          network applets.
