config BUSYBOX_CONFIG_ACPID
bool "acpid (9 kb)"
default BUSYBOX_DEFAULT_ACPID
select BUSYBOX_CONFIG_PLATFORM_LINUX
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.

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.

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.

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.

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.

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

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_SWITCH_ROOT
bool "switch_root (5.5 kb)"
default BUSYBOX_DEFAULT_SWITCH_ROOT
select BUSYBOX_CONFIG_PLATFORM_LINUX
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.

default BUSYBOX_DEFAULT_FEATURE_MOUNT_LOOP

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".)

Linux kernels >= 2.6.24 support unlimited loopback devices. They are

default BUSYBOX_DEFAULT_FEATURE_MTAB_SUPPORT
depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT
select BUSYBOX_CONFIG_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.
