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 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_LONG_OPTIONS + bool "Support long options (--hctosys,...)" + default n + depends on BUSYBOX_CONFIG_HWCLOCK && BUSYBOX_CONFIG_GETOPT_LONG + 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_FEATURE_HWCLOCK_ADJTIME_FHS + bool "Use FHS /var/lib/hwclock/adjtime" + default n + depends on BUSYBOX_CONFIG_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. + + http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLIBHWCLOCKSTATEDIRECTORYFORHWCLO + +config BUSYBOX_CONFIG_IPCRM + bool "ipcrm" + default n + select BUSYBOX_CONFIG_FEATURE_SUID + help + The ipcrm utility allows the removal of System V interprocess + communication (IPC) objects and the associated data structures + from the system. + +config BUSYBOX_CONFIG_IPCS + bool "ipcs" + default n + select BUSYBOX_CONFIG_FEATURE_SUID + help + The ipcs utility is used to provide information on the currently + allocated System V interprocess (IPC) objects in the system. + +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_MDEV + bool "mdev" + default n + help + mdev is a mini-udev implementation: call it with -s to populate + /dev from /sys, then "echo /sbin/mdev > /proc/sys/kernel/hotplug" to + have it handle hotplug events afterwards. Device names are taken + from sysfs. + +config BUSYBOX_CONFIG_FEATURE_MDEV_CONF + bool "Support /etc/mdev.conf" + default n + depends on BUSYBOX_CONFIG_MDEV + help + The mdev config file contains lines that look like: + + hd[a-z][0-9]* 0:3 660 + + That's device name (with regex match), uid:gid, and permissions. + + Config file parsing stops on the first matching line. If no config + entry is matched, devices are created with default 0:0 660. (Make + the last line match .* to override this.) + +config BUSYBOX_CONFIG_FEATURE_MDEV_EXEC + bool "Support command execution at device addition/removal" + default n + depends on BUSYBOX_CONFIG_FEATURE_MDEV_CONF + help + This adds support for an optional field to /etc/mdev.conf, consisting + of a special character and a command line to run after creating the + corresponding device(s) and before removing, ala: + + hdc root:cdrom 660 *ln -s $MDEV cdrom + + The $MDEV environment variable is set to the name of the device. + + The special characters and their meanings are: + @ Run after creating the device. + $ Run before removing the device. + * Run both after creating and before removing the device. + + Commands are executed via system() so you need /bin/sh, meaning you + probably want to select a default shell in the Shells menu. + +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_FEATURE_MKSWAP_V0 + bool "version 0 support" + default n + depends on BUSYBOX_CONFIG_MKSWAP +# depends on BUSYBOX_CONFIG_MKSWAP && BUSYBOX_CONFIG_DEPRECATED + help + Enable support for the old v0 style. + If your kernel is older than 2.1.117, then v0 support is the + only option. + +config BUSYBOX_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. + +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_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_CONFIG_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_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'. + + Note: This is for initrd in linux 2.4. Under initramfs (introduced + in linux 2.6) use switch_root instead. + +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_READPROFILE + bool "readprofile" + default n + help + This allows you to parse /proc/profile for basic profiling. + +config BUSYBOX_CONFIG_SETARCH + bool "setarch" + default n + help + The linux32 utility is used to create a 32bit environment for the + specified program (usually a shell). It only makes sense to have + this util on a system that supports both 64bit and 32bit userland + (like amd64/x86, ppc64/ppc, sparc64/sparc, etc...). + +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_SWITCH_ROOT + bool "switch_root" + 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_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_UMOUNT_ALL + bool "umount -a option" + default y + depends on BUSYBOX_CONFIG_UMOUNT + help + Support -a option to unmount all currently mounted filesystems. + +comment "Common options for mount/umount" + depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT + +config BUSYBOX_CONFIG_FEATURE_MOUNT_LOOP + bool "Support loopback mounts" + default y + depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_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_CONFIG_FEATURE_MTAB_SUPPORT + bool "Support for the old /etc/mtab file" + default n + depends on BUSYBOX_CONFIG_MOUNT || BUSYBOX_CONFIG_UMOUNT + 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 writeable, 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. + +endmenu + |
