config CONFIG_DMESG

bool "dmesg"

default n
|
|
help
|
|
dmesg is used to examine or control the kernel ring buffer. When the
|
|
Linux kernel prints messages to the system log, they are stored in
|
|
the kernel ring buffer. You can use dmesg to print the kernel's ring
|
|
buffer, clear the kernel ring buffer, change the size of the kernel
|
|
ring buffer, and change the priority level at which kernel messages
|
|
are also logged to the system console. Enable this option if you
|
|
wish to enable the 'dmesg' utility.

fbset is used to show or change the settings of a Linux frame buffer

device. The frame buffer device provides a simple and unique

interface to access a graphic display. Enable this option if you wish

to enable the 'fbset' utility.

This option enables extended fbset options, allowing one to set the

|
|
device to pre-defined video modes.

config CONFIG_FDFLUSH

bool "fdflush"

default n
|

help
|
|
Fdflush is only needed when changing media on slightly-broken
|
|
removable media drives. It is used to make Linux believe that a
|
|
hardware disk-change switch has been actuated, which causes Linux to
|
|
forget anything it has cached from the previous media. If you have
|
|
such a slightly-broken drive, you will need to run fdflush every time
|
|
you change a disk. Most people have working hardware and can safely
|
|
say leave this disabled.

The fdisk utility is used to divide hard disks into one or more

logical disks, which are generally called partitions. This utility

'disk slices' that are defined on a hard drive.

Enabling this option allows you to do terribly unsafe things like

reason you would be wise to leave this disabled.

help
|
|
Linux allows you to create ramdisks. This utility allows you to
|
|
delete them and completely free all memory that was used for the
|
|
ramdisk. For example, if you boot Linux into a ramdisk and later
|
|
pivot_root, you may want to free the memory that is allocated to the
|
|
ramdisk. If you have no use for freeing memory from a ramdisk, leave
|

this disabled.

config CONFIG_FSCK_MINIX

The minix filesystem is a nice, small, compact, read-write filesystem
|
|
with little overhead. It is not a journaling filesystem however and
|
|
can encounted corruption if it is not properly unmounted or if the

power goes off in the middle of a write. This utility allows you to

check for and attempt to repair any corruption that occurs to a minix

filesystem.

config CONFIG_GETOPT

bool "getopt"
|

default n
|

help
|
|
The getopt utility is used to break up (parse) options in command
|
|
lines to make it easy to write complex shell scripts that also check
|
|
for legal (and illegal) options. If you want to write horribly
|
|
complex shell scripts, or use some horribly complex shell script
|
|
written by others, this utility may be for you. Most people will

wisely leave this disabled.

config CONFIG_HEXDUMP

config CONFIG_HWCLOCK
|
|
bool "hwclock"

help
|

The hwclock utility is used to read and set the hardware clock
|
|
on a system. This is primarily used to set the correct time in
|
|
the hardware close, so the hardware will keep the correct time
|
|
when Linux is _not_ running.

By default, the hwclock utility only uses short options. If you

then enable this option.
|

config CONFIG_LOSETUP

bool "losetup"

default n
|

help
|

losetup is used to associate or detach a loop device with a regular
|
|
file or block device, and to query the status of a loop device. This
|
|
version does not currently support enabling data encryption.
|
|
|
|
config CONFIG_MKSWAP
|
|
bool "mkswap"
|
|
default n
|
|
help
|
|
The mkswap utility is used to configure a file or disk partition as
|
|
Linux swap space. This allows Linux to use the entire file or
|
|
partition as if it were additional RAM, which can greatly increase
|
|
the capability of low-memory machines. This additional memory is
|
|
much slower than real RAM, but can be very helpful at preventing your
|
|
applications being killed by the Linux out of memory (OOM) killer. Once
|
|
you have created swap space using 'mkswap' you need to enable the swap
|
|
space using the 'swapon' utility.
|
|
|
|
config CONFIG_MORE
|
|
bool "more"
|
|
default n
|
|
help
|
|
More is a simple utility which allows you to read text one screen
|
|
sized page at a time. If you want to read text that is larger than
|
|
the screen, and you are using anything faster than a 300 baud modem,
|
|
you will probably find this utility very helpful. If you don't have
|
|
any need to reading text files, you can leave this disabled.

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 with be especially primitive and
|
|
will be unable to determine the current screen size, and will be

unable to move the cursor.

help
|
|
This option allows utilities such as 'ls' and 'more' to determine the
|
|
width of the screen, which can allow them to display additional text
|
|
or avoid wrapping text onto the next line. If you leave this
|
|
disabled, your utilities will be especially primitive and will be

unable to determine the current screen width.

config CONFIG_PIVOT_ROOT

|
bool "pivot_root"
|
|
default n
|
|
help
|
|
The pivot_root utility swaps the mount points for the root filesystem
|
|
with some other mounted filesystem. This allows you to do all sorts
|
|
of wild and crazy things with your Linux system and is far more
|
|
powerful than 'chroot'.
|
|
|
|
config CONFIG_RDATE
|

bool "rdate"

default n

help
|
|
The rdate utility allows you to syncronize the date and time of your
|
|
system clock with the date and time of a remote networked system using
|
|
the RFC868 protocol, which is built into the inetd daemon on most
|
|
systems.

config CONFIG_SWAPONOFF
|
|
bool "swaponoff"
|
|
default n
|
|
help
|
|
This option enables both the 'swapon' and the 'swapoff' utilities.
|
|
Once you have created some swap space using 'mkswap', you also need
|
|
to enable your swap space with the 'swapon' utility. The 'swapoff'
|
|
utility is used, typically at system shutdown, to disable any swap
|
|
space. If you are not using any swap space, you can leave this
|
|
option disabled.

config CONFIG_MOUNT

help
|
|
All files and filesystems in Unix are arranged into one big directory
|
|
tree. The 'mount' utility is used to graft a filesystem onto a
|
|
particular part of the tree. A filesystem can either live on a block
|
|
device, or it can be accessible over the network, as is the case with
|
|
NFS filesystems. Most people using BusyBox will also want to enable

the 'mount' utility.

When you want to remove a mounted filesystem from its current mount point,

Enabling this feature allows mount to use the '-o' loop options,
