menu "Linux System Utilities"
config BUSYBOX_CONFIG_DMESG
bool "dmesg"
default y
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.
config BUSYBOX_CONFIG_FBSET
bool "fbset"
default n
help
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 graphics display. Enable this option
if you wish to enable the 'fbset' utility.
config BUSYBOX_CONFIG_FEATURE_FBSET_FANCY
bool " Turn on extra fbset options"
default n
depends on BUSYBOX_CONFIG_FBSET
help
This option enables extended fbset options, allowing one to set the
framebuffer size, color depth, etc. interface to access a graphics
display. Enable this option if you wish to enable extended fbset
options.
config BUSYBOX_CONFIG_FEATURE_FBSET_READMODE
bool " Turn on fbset readmode support"
default n
depends on BUSYBOX_CONFIG_FBSET
help
This option allows fbset to read the video mode database stored by
default n /etc/fb.modes, which can be used to set frame buffer
device to pre-defined video modes.
config BUSYBOX_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
leave this disabled.
config BUSYBOX_CONFIG_FDFORMAT
bool "fdformat"
default n
help
fdformat is used to low-level format a floppy disk.
config BUSYBOX_CONFIG_FDISK
bool "fdisk"
default n
help
The fdisk utility is used to divide hard disks into one or more
logical disks, which are generally called partitions. This utility
can be used to list and edit the set of partitions or BSD style
'disk slices' that are defined on a hard drive.
config BUSYBOX_FDISK_SUPPORT_LARGE_DISKS
bool
default y
depends on BUSYBOX_CONFIG_FDISK
help
Enable this option to support large disks > 4GB.
config BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
bool " Write support"
default n
depends on BUSYBOX_CONFIG_FDISK
help
Enabling this option allows you to create or change a partition table
and write those changes out to disk. If you leave this option
disabled, you will only be able to view the partition table.
config BUSYBOX_CONFIG_FEATURE_AIX_LABEL
bool " Support AIX disklabels"
default n
depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
help
Enabling this option allows you to create or change AIX disklabels.
Most people can safely leave this option disabled.
config BUSYBOX_CONFIG_FEATURE_SGI_LABEL
bool " Support SGI disklabels"
default n
depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
help
Enabling this option allows you to create or change SGI disklabels.
Most people can safely leave this option disabled.
config BUSYBOX_CONFIG_FEATURE_SUN_LABEL
bool " Support SUN disklabels"
default n
depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
help
Enabling this option allows you to create or change SUN disklabels.
Most people can safely leave this option disabled.
config BUSYBOX_CONFIG_FEATURE_OSF_LABEL
bool " Support BSD disklabels"
default n
depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
help
Enabling this option allows you to create or change BSD disklabels
and define and edit BSD disk slices.
config BUSYBOX_CONFIG_FEATURE_FDISK_ADVANCED
bool " Support expert mode"
default n
depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE
help
Enabling this option allows you to do terribly unsafe things like
define arbitrary drive geometry, move the beginning of data in a
partition, and similarly evil things. Unless you have a very good
reason you would be wise to leave this disabled.
config BUSYBOX_CONFIG_FREERAMDISK
bool "freeramdisk"
default n
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 BUSYBOX_CONFIG_FSCK_MINIX
bool "fsck_minix"
default n
help
The minix filesystem is a nice, small, compact, read-write filesystem
with little overhead. It is not a journaling filesystem however and
can experience 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 BUSYBOX_CONFIG_MKFS_MINIX
bool "mkfs_minix"
default n
help
The minix filesystem is a nice, small, compact, read-write filesystem
with little overhead. If you wish to be able to create minix filesystems
this utility will do the job for you.
comment "Minix filesystem support"
depends on BUSYBOX_CONFIG_FSCK_MINIX || BUSYBOX_CONFIG_MKFS_MINIX
config BUSYBOX_CONFIG_FEATURE_MINIX2
bool " Support Minix fs v2 (fsck_minix/mkfs_minix)"
default n
depends on BUSYBOX_CONFIG_FSCK_MINIX || BUSYBOX_CONFIG_MKFS_MINIX
help
If you wish to be able to create version 2 minix filesystems, enable this.
If you enabled 'mkfs_minix' then you almost certainly want to be using the
version 2 filesystem support.
config BUSYBOX_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 BUSYBOX_CONFIG_HEXDUMP
bool "hexdump"
default y
help
The hexdump utility is used to display binary data in a readable
way that is comparable to the output from most hex editors.
config BUSYBOX_CONFIG_HWCLOCK
bool "hwclock"
default n
help
The hwclock utility is used to read and set the hardware clock
on a system. This is primarily used to set the current time on
shutdown in the hardware clock, so the hardware will keep the
correct time when Linux is _not_ running.
config BUSYBOX_CONFIG_FEATURE_HWCLOCK_LONGOPTIONS
bool " Support long options (--hctosys,...)"
default n
depends on BUSYBOX_CONFIG_HWCLOCK
help
By default, the hwclock utility only uses short options. If you
are overly fond of its long options, such as --hctosys, --utc, etc)
then enable this option.
config BUSYBOX_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 BUSYBOX_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 BUSYBOX_CONFIG_MORE
bool "more"
default y
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.
config BUSYBOX_CONFIG_FEATURE_USE_TERMIOS
bool " Use termios to manipulate the screen"
default y
depends on BUSYBOX_CONFIG_MORE
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_PIVOT_ROOT
bool "pivot_root"
default y
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 BUSYBOX_CONFIG_RDATE
bool "rdate"
default y
help
The rdate utility allows you to synchronize 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 BUSYBOX_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 BUSYBOX_CONFIG_MOUNT
bool "mount"
default y
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.
config BUSYBOX_FEATURE_MOUNT_NFS
bool " Support mounting NFS file systems"
default y
depends on BUSYBOX_CONFIG_MOUNT
help
Enable mounting of NFS file systems.
config BUSYBOX_CONFIG_UMOUNT
bool "umount"
default y
help
When you want to remove a mounted filesystem from its current mount point,
for example when you are shutting down the system, the 'umount' utility is
the tool to use. If you enabled the 'mount' utility, you almost certainly
also want to enable 'umount'.
config BUSYBOX_CONFIG_FEATURE_MOUNT_FORCE
bool " Support forced filesystem unmounting"
default y
depends on BUSYBOX_CONFIG_UMOUNT
help
This allows you to _force_ a filesystem to be umounted. This is generally
only useful when you want to get rid of an unreachable NFS system.
comment "Common options for mount/umount"
depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT
config BUSYBOX_CONFIG_FEATURE_MOUNT_LOOP
bool " Support for loop devices"
default y
depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT
help
Enabling this feature allows mount to use the '-o' loop options,
which lets you loop mount files. Mount will automagically setup and
free the necessary loop devices so you do not need to mess with the
'losetup' utility unless you really want to. This is really
only useful if you plan to loop mount files.
config BUSYBOX_CONFIG_FEATURE_MTAB_SUPPORT
bool " Support for a real /etc/mtab (instead of /proc/mounts)"
default n
depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT
help
If your root filesystem is writable and you wish to have the 'mount'
utility create an mtab file listing the filesystems which have been
mounted then you should enable this option. Most people that use
BusyBox have a read-only root filesystem, so they will leave this
option disabled and BusyBox will use the /proc/mounts file.
config BUSYBOX_CONFIG_FEATURE_MTAB_FILENAME
string " mtab file location"
default n
depends on BUSYBOX_CONFIG_FEATURE_MTAB_SUPPORT
help
Some people have a read only root filesystem, but they also wish to
have the 'mount' utility create an mtab file listing the filesystems
which have been mounted. This option allows you to specify an alternative
location for the mtab file, such as /var/mtab, or /tmp/mtab. The default
value is /etc/mtab, which is where this file is located on most desktop
Linux systems.
