11 default BUSYBOX_DEFAULT_ACPID
12 select BUSYBOX_CONFIG_PLATFORM_LINUX
14 acpid listens to ACPI events coming either in textual form from
15 /proc/acpi/event (though it is marked deprecated it is still widely
16 used and _is_ a standard) or in binary form from specified evdevs
17 (just use /dev/input/event*).
19 It parses the event to retrieve ACTION and a possible PARAMETER.
20 It then spawns /etc/acpi/<ACTION>[/<PARAMETER>] either via run-parts
21 (if the resulting path is a directory) or directly as an executable.
23 N.B. acpid relies on run-parts so have the latter installed.

60 select BUSYBOX_CONFIG_PLATFORM_LINUX
62 dmesg is used to examine or control the kernel ring buffer. When the
63 Linux kernel prints messages to the system log, they are stored in
64 the kernel ring buffer. You can use dmesg to print the kernel's ring
65 buffer, clear the kernel ring buffer, change the size of the kernel
66 ring buffer, and change the priority level at which kernel messages
67 are also logged to the system console. Enable this option if you
68 wish to enable the 'dmesg' utility.

130 config BUSYBOX_CONFIG_FDISK
132 default BUSYBOX_DEFAULT_FDISK
133 select BUSYBOX_CONFIG_PLATFORM_LINUX
135 The fdisk utility is used to divide hard disks into one or more
136 logical disks, which are generally called partitions. This utility
137 can be used to list and edit the set of partitions or BSD style
138 'disk slices' that are defined on a hard drive.

151 depends on BUSYBOX_CONFIG_FDISK
153 Enabling this option allows you to create or change a partition table
154 and write those changes out to disk. If you leave this option
155 disabled, you will only be able to view the partition table.
157 config BUSYBOX_CONFIG_FEATURE_AIX_LABEL
158 bool "Support AIX disklabels"
159 default BUSYBOX_DEFAULT_FEATURE_AIX_LABEL
160 depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE

202 Enabling this option allows you to do terribly unsafe things like
203 define arbitrary drive geometry, move the beginning of data in a
204 partition, and similarly evil things. Unless you have a very good
205 reason you would be wise to leave this disabled.

222 default BUSYBOX_DEFAULT_FDFLUSH
223 select BUSYBOX_CONFIG_PLATFORM_LINUX
225 fdflush is only needed when changing media on slightly-broken
226 removable media drives. It is used to make Linux believe that a
227 hardware disk-change switch has been actuated, which causes Linux to
228 forget anything it has cached from the previous media. If you have
229 such a slightly-broken drive, you will need to run fdflush every time
230 you change a disk. Most people have working hardware and can safely

235 default BUSYBOX_DEFAULT_FREERAMDISK
236 select BUSYBOX_CONFIG_PLATFORM_LINUX
238 Linux allows you to create ramdisks. This utility allows you to
239 delete them and completely free all memory that was used for the
240 ramdisk. For example, if you boot Linux into a ramdisk and later
241 pivot_root, you may want to free the memory that is allocated to the
242 ramdisk. If you have no use for freeing memory from a ramdisk, leave
244 config BUSYBOX_CONFIG_FSCK_MINIX
246 default BUSYBOX_DEFAULT_FSCK_MINIX
248 The minix filesystem is a nice, small, compact, read-write filesystem
249 with little overhead. It is not a journaling filesystem however and
250 can experience corruption if it is not properly unmounted or if the
251 power goes off in the middle of a write. This utility allows you to
252 check for and attempt to repair any corruption that occurs to a minix
254 config BUSYBOX_CONFIG_FSTRIM
256 default BUSYBOX_DEFAULT_FSTRIM
257 select BUSYBOX_CONFIG_PLATFORM_LINUX
259 Discard unused blocks on a mounted filesystem.
260 config BUSYBOX_CONFIG_GETOPT
262 default BUSYBOX_DEFAULT_GETOPT
264 The getopt utility is used to break up (parse) options in command
265 lines to make it easy to write complex shell scripts that also check
266 for legal (and illegal) options. If you want to write horribly
267 complex shell scripts, or use some horribly complex shell script
268 written by others, this utility may be for you. Most people will
269 wisely leave this disabled.

285 bool "Support -R, reverse of 'hexdump -Cv'"
286 default BUSYBOX_DEFAULT_FEATURE_HEXDUMP_REVERSE
287 depends on BUSYBOX_CONFIG_HEXDUMP
289 The hexdump utility is used to display binary data in an ascii
290 readable way. This option creates binary data from an ascii input.
291 NB: this option is non-standard. It's unwise to use it in scripts
292 aimed to be portable.
294 config BUSYBOX_CONFIG_HD
296 default BUSYBOX_DEFAULT_HD
298 hd is an alias to hexdump -C.
299 config BUSYBOX_CONFIG_HWCLOCK
301 default BUSYBOX_DEFAULT_HWCLOCK
302 select BUSYBOX_CONFIG_PLATFORM_LINUX
304 The hwclock utility is used to read and set the hardware clock
305 on a system. This is primarily used to set the current time on
306 shutdown in the hardware clock, so the hardware will keep the
307 correct time when Linux is _not_ running.
309 config BUSYBOX_CONFIG_FEATURE_HWCLOCK_LONG_OPTIONS
310 bool "Support long options (--hctosys,...)"
311 default BUSYBOX_DEFAULT_FEATURE_HWCLOCK_LONG_OPTIONS
312 depends on BUSYBOX_CONFIG_HWCLOCK && BUSYBOX_CONFIG_LONG_OPTS
314 By default, the hwclock utility only uses short options. If you
315 are overly fond of its long options, such as --hctosys, --utc, etc)
316 then enable this option.

323 Starting with FHS 2.3, the adjtime state file is supposed to exist
324 at /var/lib/hwclock/adjtime instead of /etc/adjtime. If you wish
325 to use the FHS behavior, answer Y here, otherwise answer N for the
326 classic /etc/adjtime path.

417 bool "Support loading of firmwares"
418 default BUSYBOX_DEFAULT_FEATURE_MDEV_LOAD_FIRMWARE
419 depends on BUSYBOX_CONFIG_MDEV
421 Some devices need to load firmware before they can be usable.
423 These devices will request userspace look up the files in
424 /lib/firmware/ and if it exists, send it to the kernel for
425 loading into the hardware.

453 If you wish to be able to create version 2 minix filesystems, enable
454 this. If you enabled 'mkfs_minix' then you almost certainly want to
455 be using the version 2 filesystem support.

476 config BUSYBOX_CONFIG_MKSWAP
478 default BUSYBOX_DEFAULT_MKSWAP
480 The mkswap utility is used to configure a file or disk partition as
481 Linux swap space. This allows Linux to use the entire file or
482 partition as if it were additional RAM, which can greatly increase
483 the capability of low-memory machines. This additional memory is
484 much slower than real RAM, but can be very helpful at preventing your
485 applications being killed by the Linux out of memory (OOM) killer.
486 Once you have created swap space using 'mkswap' you need to enable
487 the swap space using the 'swapon' utility.

497 default BUSYBOX_DEFAULT_MORE
499 more is a simple utility which allows you to read text one screen
500 sized page at a time. If you want to read text that is larger than
501 the screen, and you are using anything faster than a 300 baud modem,
502 you will probably find this utility very helpful. If you don't have
503 any need to reading text files, you can leave this disabled.

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

537 Enable mounting of virtual file systems via external helpers.
538 E.g. "mount obexfs#-b00.11.22.33.44.55 /mnt" will in effect call
539 "obexfs -b00.11.22.33.44.55 /mnt"
540 Also "mount -t sometype [-o opts] fs /mnt" will try
541 "sometype [-o opts] fs /mnt" if simple mount syscall fails.
542 The idea is to use such virtual filesystems in /etc/fstab.

545 bool "Support specifying devices by label or UUID"
546 default BUSYBOX_DEFAULT_FEATURE_MOUNT_LABEL
547 depends on BUSYBOX_CONFIG_MOUNT
548 select BUSYBOX_CONFIG_VOLUMEID
550 This allows for specifying a device by label or uuid, rather than by
551 name. This feature utilizes the same functionality as blkid/findfs.
552 This also enables label or uuid support for swapon.

614 default BUSYBOX_DEFAULT_PIVOT_ROOT
615 select BUSYBOX_CONFIG_PLATFORM_LINUX
617 The pivot_root utility swaps the mount points for the root filesystem
618 with some other mounted filesystem. This allows you to do all sorts
619 of wild and crazy things with your Linux system and is far more
620 powerful than 'chroot'.
622 Note: This is for initrd in linux 2.4. Under initramfs (introduced
623 in linux 2.6) use switch_root instead.
624 config BUSYBOX_CONFIG_RDATE

724 default BUSYBOX_DEFAULT_SWITCH_ROOT
725 select BUSYBOX_CONFIG_PLATFORM_LINUX
727 The switch_root utility is used from initramfs to select a new
728 root device. Under initramfs, you have to use this instead of
729 pivot_root. (Stop reading here if you don't care why.)
731 Booting with initramfs extracts a gzipped cpio archive into rootfs
732 (which is a variant of ramfs/tmpfs). Because rootfs can't be moved
733 or unmounted*, pivot_root will not work from initramfs. Instead,
734 switch_root deletes everything out of rootfs (including itself),
735 does a mount --move that overmounts rootfs with the new root, and
736 then execs the specified init program.
738 * Because the Linux kernel uses rootfs internally as the starting
739 and ending point for searching through the kernel's doubly linked
740 list of active mount points. That's why.

780 Enabling this feature allows automatic mounting of files (containing
781 filesystem images) via the linux kernel's loopback devices.
782 The mount command will detect you are trying to mount a file instead
783 of a block device, and transparently associate the file with a
784 loopback device. The umount command will also free that loopback
787 You can still use the 'losetup' utility (to manually associate files
788 with loop devices) if you need to do something advanced, such as
789 specify an offset or cryptographic options to the loopback device.

810 Historically, Unix systems kept track of the currently mounted
811 partitions in the file "/etc/mtab". These days, the kernel exports
812 the list of currently mounted partitions in "/proc/mounts", rendering
813 the old mtab file obsolete. (In modern systems, /etc/mtab should be
814 a symlink to /proc/mounts.)
816 The only reason to have mount maintain an /etc/mtab file itself is if
817 your stripped-down embedded system does not have a /proc directory.
818 If you must use this, keep in mind it's inherently brittle (for
819 example a mount under chroot won't update it), can't handle modern
820 features like separate per-process filesystem namespaces, requires
821 that your /etc directory be writable, tends to get easily confused
822 by --bind or --move mounts, won't update if you rename a directory
823 that contains a mount point, and so on. (In brief: avoid.)
825 About the only reason to use this is if you've removed /proc from
