config BUSYBOX_ACPID
	bool "acpid (9 kb)"
	default y
	help
	acpid listens to ACPI events coming either in textual form from
	/proc/acpi/event (though it is marked deprecated it is still widely
	used and _is_ a standard) or in binary form from specified evdevs
	(just use /dev/input/event*).

	It parses the event to retrieve ACTION and a possible PARAMETER.
	It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
	(if the resulting path is a directory) or directly as an executable.

	N.B. acpid relies on run-parts so have the latter installed.

	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.

	default y
	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_FREERAMDISK
	bool "freeramdisk (1.3 kb)"
	default y
	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_FSCK_MINIX
	bool "fsck.minix (13 kb)"
	default y

config BUSYBOX_GETOPT
	bool "getopt (5.8 kb)"
	default y
	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_FEATURE_GETOPT_LONG

	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_FEATURE_HWCLOCK_ADJTIME_FHS
	bool "Use FHS /var/lib/hwclock/adjtime"
	default n  # util-linux-ng in Fedora 13 still uses /etc/adjtime
	depends on BUSYBOX_HWCLOCK
	help
	Starting with FHS 2.3, the adjtime state file is supposed to exist
	at /var/lib/hwclock/adjtime instead of /etc/adjtime. If you wish
	to use the FHS behavior, answer Y here, otherwise answer N for the
	classic /etc/adjtime path.

	loading into the hardware.

config BUSYBOX_FEATURE_MDEV_DAEMON
	bool "Support daemon mode"
	default y
	depends on BUSYBOX_MDEV
	help
	Adds the -d option to run mdev in daemon mode handling hotplug
	events from the kernel like udev. If the system generates many
	hotplug events this mode of operation will consume less
	resources than registering mdev as hotplug helper or using the
	uevent applet.
config BUSYBOX_MESG
	bool "mesg (1.4 kb)"
	default y

	bool "Enable writing to tty only by group, not by everybody"
	default y
	depends on BUSYBOX_MESG
	help
	Usually, ttys are owned by group "tty", and "write" tool is
	setgid to this group. This way, "mesg y" only needs to enable
	"write by owning group" bit in tty mode.

config BUSYBOX_MKSWAP
	bool "mkswap (6.3 kb)"
	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_FEATURE_MKSWAP_UUID
	bool "UUID support"
	default y
	depends on BUSYBOX_MKSWAP
	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_MOUNT
	bool "mount (23 kb)"
	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.

config BUSYBOX_FEATURE_MOUNT_FAKE
	bool "Support -f (fake mount)"
	default y

	to the kernel.

config BUSYBOX_FEATURE_MOUNT_HELPERS
	bool "Support mount helpers"
	default n
	depends on BUSYBOX_MOUNT
	help
	Enable mounting of virtual file systems via external helpers.
	E.g. "mount obexfs#-b00.11.22.33.44.55 /mnt" will in effect call
	"obexfs -b00.11.22.33.44.55 /mnt"
	Also "mount -t sometype [-o opts] fs /mnt" will try
	"sometype [-o opts] fs /mnt" if simple mount syscall fails.
	The idea is to use such virtual filesystems in /etc/fstab.

config BUSYBOX_FEATURE_MOUNT_LABEL
	bool "Support specifying devices by label or UUID"
	default y
	depends on BUSYBOX_MOUNT
	select BUSYBOX_VOLUMEID

	bool "Support mounting NFS file systems on Linux < 2.6.23"
	default n
	depends on BUSYBOX_MOUNT
	select BUSYBOX_FEATURE_SYSLOG
	help
	Enable mounting of NFS file systems on Linux kernels prior
	to version 2.6.23. Note that in this case mounting of NFS
	over IPv6 will not be possible.

	Note that this option links in RPC support from libc,
	which is rather large (~10 kbytes on uclibc).

config BUSYBOX_FEATURE_MOUNT_CIFS
	bool "Support mounting CIFS/SMB file systems"
	default y
	depends on BUSYBOX_MOUNT
	help
	Enable support for samba mounts.

config BUSYBOX_PIVOT_ROOT
	bool "pivot_root (1.1 kb)"
	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'.

	Note: This is for initrd in linux 2.4. Under initramfs (introduced
	in linux 2.6) use switch_root instead.
config BUSYBOX_RDATE
	bool "rdate (5.6 kb)"
	default y
	help

config BUSYBOX_SETARCH
	bool "setarch (3.6 kb)"
	default y
	help
	The linux32 utility is used to create a 32bit environment for the
	specified program (usually a shell). It only makes sense to have

	(like amd64/x86, ppc64/ppc, sparc64/sparc, etc...).

config BUSYBOX_LINUX32
	bool "linux32 (3.3 kb)"
	default y
	help
	Alias to "setarch linux32".

config BUSYBOX_LINUX64
	bool "linux64 (3.3 kb)"
	default y
	help
	Alias to "setarch linux64".
config BUSYBOX_SETPRIV
	bool "setpriv (6.6 kb)"
	default y
	select BUSYBOX_LONG_OPTS
	help
	Run a program with different Linux privilege settings.
	Requires kernel >= 3.5

config BUSYBOX_FEATURE_SETPRIV_DUMP
	bool "Support dumping current privilege state"
	default y
	depends on BUSYBOX_SETPRIV
	help
	Enables the "--dump" switch to print out the current privilege
	state. This is helpful for diagnosing problems.

config BUSYBOX_FEATURE_SETPRIV_CAPABILITIES
	bool "Support capabilities"
	default y
	depends on BUSYBOX_SETPRIV
	help
	Capabilities can be used to grant processes additional rights
	without the necessity to always execute as the root user.
	Enabling this option enables "--dump" to show information on
	capabilities.

config BUSYBOX_FEATURE_SETPRIV_CAPABILITY_NAMES
	bool "Support capability names"
	default y
	depends on BUSYBOX_SETPRIV && BUSYBOX_FEATURE_SETPRIV_CAPABILITIES
	help
	Capabilities can be either referenced via a human-readble name,
	e.g. "net_admin", or using their index, e.g. "cap_12". Enabling
	this option allows using the human-readable names in addition to
	the index-based names.
config BUSYBOX_SETSID
	bool "setsid (3.6 kb)"
	default y
	help
	setsid runs a program in a new session
config BUSYBOX_SWAPON
	bool "swapon (15 kb)"
	default n
	help
	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_FEATURE_SWAPON_DISCARD
	bool "Support discard option -d"
	default y
	depends on BUSYBOX_SWAPON
	help
	Enable support for discarding swap area blocks at swapon and/or as
	the kernel frees them. This option enables both the -d option on
	'swapon' and the 'discard' option for swap entries in /etc/fstab.

config BUSYBOX_FEATURE_SWAPON_PRI
	bool "Support priority option -p"
	default y
	depends on BUSYBOX_SWAPON
	help
	Enable support for setting swap device priority in swapon.

config BUSYBOX_SWAPOFF
	bool "swapoff (14 kb)"
	default n

config BUSYBOX_FEATURE_SWAPONOFF_LABEL
	bool "Support specifying devices by label or UUID"
	default y
	depends on BUSYBOX_SWAPON || BUSYBOX_SWAPOFF
	select BUSYBOX_VOLUMEID
	help
	This allows for specifying a device by label or uuid, rather than by
	name. This feature utilizes the same functionality as blkid/findfs.
config BUSYBOX_SWITCH_ROOT
	bool "switch_root (5.5 kb)"
	default y
	help
	The switch_root utility is used from initramfs to select a new
	root device. Under initramfs, you have to use this instead of
	pivot_root. (Stop reading here if you don't care why.)

	Booting with initramfs extracts a gzipped cpio archive into rootfs
	(which is a variant of ramfs/tmpfs). Because rootfs can't be moved
	or unmounted*, pivot_root will not work from initramfs. Instead,
	switch_root deletes everything out of rootfs (including itself),
	does a mount --move that overmounts rootfs with the new root, and
	then execs the specified init program.

	* Because the Linux kernel uses rootfs internally as the starting
	and ending point for searching through the kernel's doubly linked
	list of active mount points. That's why.

config BUSYBOX_TASKSET
	bool "taskset (4.2 kb)"
	default y
	help
	Retrieve or set a processes's CPU affinity.
	This requires sched_{g,s}etaffinity support in your libc.

config BUSYBOX_FEATURE_TASKSET_FANCY
	bool "Fancy output"
	default y
	depends on BUSYBOX_TASKSET
	help
	Needed for machines with more than 32-64 CPUs:
	affinity parameter 0xHHHHHHHHHHHHHHHHHHHH can be arbitrarily long
	in this case. Otherwise, it is limited to sizeof(long).

config BUSYBOX_FEATURE_TASKSET_CPULIST
	bool "CPU list support (-c option)"
	default y
	depends on BUSYBOX_FEATURE_TASKSET_FANCY
	help
	Add support for taking/printing affinity as CPU list when '-c'
	option is used. For example, it prints '0-3,7' instead of mask '8f'.
config BUSYBOX_UEVENT
	bool "uevent (3.1 kb)"
	default y
	help
	uevent is a netlink listener for kernel uevent notifications
	sent via netlink. It is usually used for dynamic device creation.
config BUSYBOX_UMOUNT
	bool "umount (5.1 kb)"
	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_FEATURE_UMOUNT_ALL
	bool "Support -a (unmount all)"
	default y
	depends on BUSYBOX_UMOUNT
	help
	Support -a option to unmount all currently mounted filesystems.
config BUSYBOX_UNSHARE
	bool "unshare (7.2 kb)"
	default y
	depends on !BUSYBOX_NOMMU
	select BUSYBOX_LONG_OPTS
	help
	Run program with some namespaces unshared from parent.
config BUSYBOX_WALL
	bool "wall (2.6 kb)"
	default y
	depends on BUSYBOX_FEATURE_UTMP
	help
	Write a message to all users that are logged in.

config BUSYBOX_FEATURE_MOUNT_LOOP
	bool "Support loopback mounts"
	default y
	depends on BUSYBOX_MOUNT || BUSYBOX_UMOUNT
	help
	Enabling this feature allows automatic mounting of files (containing
	filesystem images) via the linux kernel's loopback devices.
	The mount command will detect you are trying to mount a file instead
	of a block device, and transparently associate the file with a
	loopback device. The umount command will also free that loopback
	device.

	You can still use the 'losetup' utility (to manually associate files
	with loop devices) if you need to do something advanced, such as
	specify an offset or cryptographic options to the loopback device.
	(If you don't want umount to free the loop device, use "umount -D".)

config BUSYBOX_FEATURE_MOUNT_LOOP_CREATE
	bool "Create new loopback devices if needed"
	default y
	depends on BUSYBOX_FEATURE_MOUNT_LOOP
	help
	Linux kernels >= 2.6.24 support unlimited loopback devices. They are
	allocated for use when trying to use a loop device. The loop device
	must however exist.

	This feature lets mount to try to create next /dev/loopN device
	if it does not find a free one.

config BUSYBOX_FEATURE_MTAB_SUPPORT
	bool "Support old /etc/mtab file"
	default n
	depends on BUSYBOX_MOUNT || BUSYBOX_UMOUNT
	select BUSYBOX_FEATURE_MOUNT_FAKE
	help
	Historically, Unix systems kept track of the currently mounted
	partitions in the file "/etc/mtab". These days, the kernel exports
	the list of currently mounted partitions in "/proc/mounts", rendering
	the old mtab file obsolete. (In modern systems, /etc/mtab should be
	a symlink to /proc/mounts.)

	The only reason to have mount maintain an /etc/mtab file itself is if
	your stripped-down embedded system does not have a /proc directory.
	If you must use this, keep in mind it's inherently brittle (for
	example a mount under chroot won't update it), can't handle modern
	features like separate per-process filesystem namespaces, requires
	that your /etc directory be writable, tends to get easily confused
	by --bind or --move mounts, won't update if you rename a directory
	that contains a mount point, and so on. (In brief: avoid.)

	About the only reason to use this is if you've removed /proc from
	your kernel.
