    13     Minimum allowable password length.

    20     Trade binary size versus speed for the md5sum algorithm.
    21     Approximate values running uClibc and hashing
    22     linux-2.4.4.tar.bz2 were:

    29 niro 816 config FEATURE_FAST_TOP
    30     bool "Faster /proc scanning code (+100 bytes)"
    31     default n
    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 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 FEATURE_EDITING
    45     bool "Command line editing"
    46     default n

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

    51     int "Maximum length of input"
    52     range 128 8192
    53     default 1024
    54     depends on 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 FEATURE_EDITING_VI
    61     bool "vi-style line editing commands"
    62     default n
    63     depends on 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".
    67    
    68     config FEATURE_EDITING_HISTORY

    84     bool "Tab completion"

    92     default n
    93     depends on FEATURE_TAB_COMPLETION
    94     help
    95     Enable username completion.

    97     config FEATURE_EDITING_FANCY_PROMPT
    98     bool "Fancy shell prompts"
    99     default n
    100     depends on FEATURE_EDITING
    101     help
    102     Setting this option allows for prompts to use things like \w and
    103     \$ and escape codes.
    104    
    105     config FEATURE_VERBOSE_CP_MESSAGE
    106     bool "Give more precise messages when copy fails (cp, mv etc)"

    109     Error messages with this feature enabled:
    110     $ cp file /does_not_exist/file
    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.

    120     config FEATURE_COPYBUF_KB
    121     int "Copy buffer size, in kilobytes"
    122     range 1 1024
    123     default 4
    124     help
    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 MONOTONIC_SYSCALL
    131     bool "Use clock_gettime(CLOCK_MONOTONIC) syscall"
    132     default y
    133     help
    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 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    
    148     config FEATURE_HWIB
    149     bool "Support infiniband HW"
    150     default y

    153     network applets.
