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"
	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
	  1                   1.4                5392
	  2                   3.0                5088
	  3 (smallest)        5.1                4912

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_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 remove '/does_not_exist/file': No such file or directory
	    cp: cannot stat '/vmlinuz/file': Not a directory
	  respectively.
	  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.
