It parses the event to retrieve ACTION and a possible PARAMETER. It then spawns /etc/acpi/[/] 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. config BUSYBOX_CONFIG_FEATURE_ACPID_COMPAT bool "Accept and ignore redundant options" default BUSYBOX_DEFAULT_FEATURE_ACPID_COMPAT depends on BUSYBOX_CONFIG_ACPID help Accept and ignore compatibility options -g -m -s -S -v. config BUSYBOX_CONFIG_BLKDISCARD bool "blkdiscard (4.3 kb)" default BUSYBOX_DEFAULT_BLKDISCARD help blkdiscard discards sectors on a given device. config BUSYBOX_CONFIG_BLKID bool "blkid (12 kb)" default BUSYBOX_DEFAULT_BLKID select BUSYBOX_CONFIG_VOLUMEID help Lists labels and UUIDs of all filesystems. config BUSYBOX_CONFIG_FEATURE_BLKID_TYPE bool "Print filesystem type" default BUSYBOX_DEFAULT_FEATURE_BLKID_TYPE depends on BUSYBOX_CONFIG_BLKID help Show TYPE="filesystem type" config BUSYBOX_CONFIG_BLOCKDEV bool "blockdev (2.3 kb)" default BUSYBOX_DEFAULT_BLOCKDEV help Performs some ioctls with block devices. config BUSYBOX_CONFIG_CAL bool "cal (5.8 kb)" default BUSYBOX_DEFAULT_CAL help cal is used to display a monthly calendar. config BUSYBOX_CONFIG_CHRT bool "chrt (4.7 kb)" default BUSYBOX_DEFAULT_CHRT help Manipulate real-time attributes of a process. This requires sched_{g,s}etparam support in your libc. config BUSYBOX_CONFIG_DMESG bool "dmesg (3.7 kb)" default BUSYBOX_DEFAULT_DMESG 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_FEATURE_DMESG_PRETTY bool "Pretty output" default BUSYBOX_DEFAULT_FEATURE_DMESG_PRETTY depends on BUSYBOX_CONFIG_DMESG help If you wish to scrub the syslog level from the output, say 'Y' here. The syslog level is a string prefixed to every line with the form "<#>". With this option you will see: # dmesg Linux version 2.6.17.4 ..... BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009f000 (usable) Without this option you will see: # dmesg <5>Linux version 2.6.17.4 ..... <6>BIOS-provided physical RAM map: <6> BIOS-e820: 0000000000000000 - 000000000009f000 (usable) config BUSYBOX_CONFIG_EJECT bool "eject (4 kb)" default BUSYBOX_DEFAULT_EJECT help Used to eject cdroms. (defaults to /dev/cdrom) config BUSYBOX_CONFIG_FEATURE_EJECT_SCSI bool "SCSI support" default BUSYBOX_DEFAULT_FEATURE_EJECT_SCSI depends on BUSYBOX_CONFIG_EJECT help Add the -s option to eject, this allows to eject SCSI-Devices and usb-storage devices. config BUSYBOX_CONFIG_FALLOCATE bool "fallocate (4.1 kb)" default BUSYBOX_DEFAULT_FALLOCATE help Preallocate space for files. config BUSYBOX_CONFIG_FATATTR bool "fatattr (1.9 kb)" default BUSYBOX_DEFAULT_FATATTR help fatattr lists or changes the file attributes on a fat file system. config BUSYBOX_CONFIG_FBSET bool "fbset (5.9 kb)" default BUSYBOX_DEFAULT_FBSET 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 "Enable extra options" default BUSYBOX_DEFAULT_FEATURE_FBSET_FANCY 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 "Enable readmode support" default BUSYBOX_DEFAULT_FEATURE_FBSET_READMODE depends on BUSYBOX_CONFIG_FBSET help This option allows fbset to read the video mode database stored by default BUSYBOX_DEFAULT_FEATURE_FBSET_READMODE /etc/fb.modes, which can be used to set frame buffer device to pre-defined video modes. config BUSYBOX_CONFIG_FDFORMAT bool "fdformat (4.4 kb)" default BUSYBOX_DEFAULT_FDFORMAT help fdformat is used to low-level format a floppy disk. config BUSYBOX_CONFIG_FDISK bool "fdisk (37 kb)" default BUSYBOX_DEFAULT_FDISK 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_CONFIG_FDISK_SUPPORT_LARGE_DISKS bool "Support over 4GB disks" default BUSYBOX_DEFAULT_FDISK_SUPPORT_LARGE_DISKS depends on BUSYBOX_CONFIG_FDISK depends on !BUSYBOX_CONFIG_LFS # with LFS no special code is needed config BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE bool "Write support" default BUSYBOX_DEFAULT_FEATURE_FDISK_WRITABLE 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 BUSYBOX_DEFAULT_FEATURE_AIX_LABEL 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 BUSYBOX_DEFAULT_FEATURE_SGI_LABEL 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_OSF_LABEL bool "Support BSD disklabels" default BUSYBOX_DEFAULT_FEATURE_OSF_LABEL 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_GPT_LABEL bool "Support GPT disklabels" default BUSYBOX_DEFAULT_FEATURE_GPT_LABEL depends on BUSYBOX_CONFIG_FDISK && BUSYBOX_CONFIG_FEATURE_FDISK_WRITABLE help Enabling this option allows you to view GUID Partition Table disklabels. config BUSYBOX_CONFIG_FEATURE_FDISK_ADVANCED bool "Support expert mode" default BUSYBOX_DEFAULT_FEATURE_FDISK_ADVANCED 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_FINDFS bool "findfs (12 kb)" default BUSYBOX_DEFAULT_FINDFS select BUSYBOX_CONFIG_VOLUMEID help Prints the name of a filesystem with given label or UUID. config BUSYBOX_CONFIG_FLOCK bool "flock (6.3 kb)" default BUSYBOX_DEFAULT_FLOCK help Manage locks from shell scripts config BUSYBOX_CONFIG_FDFLUSH bool "fdflush (1.3 kb)" default BUSYBOX_DEFAULT_FDFLUSH 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_FREERAMDISK bool "freeramdisk (1.3 kb)" default BUSYBOX_DEFAULT_FREERAMDISK 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 (13 kb)" default BUSYBOX_DEFAULT_FSCK_MINIX 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_FSFREEZE bool "fsfreeze (3.5 kb)" default BUSYBOX_DEFAULT_FSFREEZE select BUSYBOX_CONFIG_LONG_OPTS help Halt new accesses and flush writes on a mounted filesystem. config BUSYBOX_CONFIG_FSTRIM bool "fstrim (4.4 kb)" default BUSYBOX_DEFAULT_FSTRIM help Discard unused blocks on a mounted filesystem. config BUSYBOX_CONFIG_GETOPT bool "getopt (5.8 kb)" default BUSYBOX_DEFAULT_GETOPT 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_FEATURE_GETOPT_LONG bool "Support -l LONGOPTs" default BUSYBOX_DEFAULT_FEATURE_GETOPT_LONG depends on BUSYBOX_CONFIG_GETOPT && BUSYBOX_CONFIG_LONG_OPTS help Enable support for long options (option -l). config BUSYBOX_CONFIG_HEXDUMP bool "hexdump (8.6 kb)" default BUSYBOX_DEFAULT_HEXDUMP 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_HD bool "hd (7.8 kb)" default BUSYBOX_DEFAULT_HD help hd is an alias to hexdump -C. config BUSYBOX_CONFIG_XXD bool "xxd (8.9 kb)" default BUSYBOX_DEFAULT_XXD help The xxd 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 (5.8 kb)" default BUSYBOX_DEFAULT_HWCLOCK 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_ADJTIME_FHS bool "Use FHS /var/lib/hwclock/adjtime" default BUSYBOX_DEFAULT_FEATURE_HWCLOCK_ADJTIME_FHS # util-linux-ng in Fedora 13 still uses /etc/adjtime 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. pathname.com/fhs/pub/fhs-2.3.html#VARLIBHWCLOCKSTATEDIRECTORYFORHWCLO config BUSYBOX_CONFIG_IONICE bool "ionice (3.8 kb)" default BUSYBOX_DEFAULT_IONICE help Set/set program io scheduling class and priority Requires kernel >= 2.6.13 config BUSYBOX_CONFIG_IPCRM bool "ipcrm (3.2 kb)" default BUSYBOX_DEFAULT_IPCRM 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 (11 kb)" default BUSYBOX_DEFAULT_IPCS help The ipcs utility is used to provide information on the currently allocated System V interprocess (IPC) objects in the system. config BUSYBOX_CONFIG_LAST bool "last (6.1 kb)" default BUSYBOX_DEFAULT_LAST depends on BUSYBOX_CONFIG_FEATURE_WTMP help 'last' displays a list of the last users that logged into the system. config BUSYBOX_CONFIG_FEATURE_LAST_FANCY bool "Output extra information" default BUSYBOX_DEFAULT_FEATURE_LAST_FANCY depends on BUSYBOX_CONFIG_LAST help 'last' displays detailed information about the last users that logged into the system (mimics sysvinit last). +900 bytes. config BUSYBOX_CONFIG_LOSETUP bool "losetup (5.5 kb)" default BUSYBOX_DEFAULT_LOSETUP 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_LSPCI bool "lspci (6.3 kb)" default BUSYBOX_DEFAULT_LSPCI help lspci is a utility for displaying information about PCI buses in the system and devices connected to them. This version uses sysfs (/sys/bus/pci/devices) only. config BUSYBOX_CONFIG_LSUSB bool "lsusb (4.2 kb)" default BUSYBOX_DEFAULT_LSUSB help lsusb is a utility for displaying information about USB buses in the system and devices connected to them. This version uses sysfs (/sys/bus/usb/devices) only. config BUSYBOX_CONFIG_MDEV bool "mdev (17 kb)" default BUSYBOX_DEFAULT_MDEV help mdev is a mini-udev implementation for dynamically creating device nodes in the /dev directory. For more information, please see docs/mdev.txt config BUSYBOX_CONFIG_FEATURE_MDEV_CONF bool "Support /etc/mdev.conf" default BUSYBOX_DEFAULT_FEATURE_MDEV_CONF depends on BUSYBOX_CONFIG_MDEV help Add support for the mdev config file to control ownership and permissions of the device nodes. For more information, please see docs/mdev.txt config BUSYBOX_CONFIG_FEATURE_MDEV_RENAME bool "Support subdirs/symlinks" default BUSYBOX_DEFAULT_FEATURE_MDEV_RENAME depends on BUSYBOX_CONFIG_FEATURE_MDEV_CONF help Add support for renaming devices and creating symlinks.

For more information, please see docs/mdev.txt config BUSYBOX_CONFIG_FEATURE_MDEV_LOAD_FIRMWARE bool "Support loading of firmware" default BUSYBOX_DEFAULT_FEATURE_MDEV_LOAD_FIRMWARE depends on BUSYBOX_CONFIG_MDEV help Some devices need to load firmware before they can be usable. These devices will request userspace look up the files in /lib/firmware/ and if it exists, send it to the kernel for loading into the hardware. config BUSYBOX_CONFIG_FEATURE_MDEV_DAEMON bool "Support daemon mode" default BUSYBOX_DEFAULT_FEATURE_MDEV_DAEMON depends on BUSYBOX_CONFIG_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_CONFIG_MESG bool "mesg (1.4 kb)" default BUSYBOX_DEFAULT_MESG help Mesg controls access to your terminal by others. It is typically used to allow or disallow other users to write to your terminal config BUSYBOX_CONFIG_FEATURE_MESG_ENABLE_ONLY_GROUP bool "Enable writing to tty only by group, not by everybody" default BUSYBOX_DEFAULT_FEATURE_MESG_ENABLE_ONLY_GROUP depends on BUSYBOX_CONFIG_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. If you set this option to N, "mesg y" will enable writing by anybody at all. This is not recommended. config BUSYBOX_CONFIG_MKE2FS bool "mke2fs (10 kb)" default BUSYBOX_DEFAULT_MKE2FS help Utility to create EXT2 filesystems. config BUSYBOX_CONFIG_MKFS_EXT2 bool "mkfs.ext2 (10 kb)" default BUSYBOX_DEFAULT_MKFS_EXT2 help Alias to "mke2fs". config BUSYBOX_CONFIG_MKFS_MINIX bool "mkfs.minix (10 kb)" default BUSYBOX_DEFAULT_MKFS_MINIX 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. config BUSYBOX_CONFIG_FEATURE_MINIX2 bool "Support Minix fs v2 (fsck_minix/mkfs_minix)" default BUSYBOX_DEFAULT_FEATURE_MINIX2 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_MKFS_REISER bool "mkfs_reiser" default BUSYBOX_DEFAULT_MKFS_REISER help Utility to create ReiserFS filesystems. Note: this applet needs a lot of testing and polishing. config BUSYBOX_CONFIG_MKDOSFS bool "mkdosfs (7.2 kb)" default BUSYBOX_DEFAULT_MKDOSFS help Utility to create FAT32 filesystems. config BUSYBOX_CONFIG_MKFS_VFAT bool "mkfs.vfat (7.2 kb)" default BUSYBOX_DEFAULT_MKFS_VFAT help Alias to "mkdosfs". config BUSYBOX_CONFIG_MKSWAP bool "mkswap (6.3 kb)" default BUSYBOX_DEFAULT_MKSWAP 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_UUID bool "UUID support" default BUSYBOX_DEFAULT_FEATURE_MKSWAP_UUID depends on BUSYBOX_CONFIG_MKSWAP help Generate swap spaces with universally unique identifiers. config BUSYBOX_CONFIG_MORE bool "more (7 kb)" default BUSYBOX_DEFAULT_MORE 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_MOUNT bool "mount (23 kb)" default BUSYBOX_DEFAULT_MOUNT 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_CONFIG_FEATURE_MOUNT_FAKE bool "Support -f (fake mount)" default BUSYBOX_DEFAULT_FEATURE_MOUNT_FAKE depends on BUSYBOX_CONFIG_MOUNT help Enable support for faking a file system mount. config BUSYBOX_CONFIG_FEATURE_MOUNT_VERBOSE bool "Support -v (verbose)" default BUSYBOX_DEFAULT_FEATURE_MOUNT_VERBOSE depends on BUSYBOX_CONFIG_MOUNT help Enable multi-level -v[vv...] verbose messages. Useful if you debug mount problems and want to see what is exactly passed to the kernel. config BUSYBOX_CONFIG_FEATURE_MOUNT_HELPERS bool "Support mount helpers" default BUSYBOX_DEFAULT_FEATURE_MOUNT_HELPERS depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_MOUNT_LABEL bool "Support specifying devices by label or UUID" default BUSYBOX_DEFAULT_FEATURE_MOUNT_LABEL depends on BUSYBOX_CONFIG_MOUNT select BUSYBOX_CONFIG_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_CONFIG_FEATURE_MOUNT_NFS bool "Support mounting NFS file systems on Linux < 2.6.23" default BUSYBOX_DEFAULT_FEATURE_MOUNT_NFS depends on BUSYBOX_CONFIG_MOUNT select BUSYBOX_CONFIG_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_CONFIG_FEATURE_MOUNT_CIFS bool "Support mounting CIFS/SMB file systems" default BUSYBOX_DEFAULT_FEATURE_MOUNT_CIFS depends on BUSYBOX_CONFIG_MOUNT help Enable support for samba mounts. config BUSYBOX_CONFIG_FEATURE_MOUNT_FLAGS depends on BUSYBOX_CONFIG_MOUNT bool "Support lots of -o flags" default BUSYBOX_DEFAULT_FEATURE_MOUNT_FLAGS help Without this, mount only supports ro/rw/remount. With this, it supports nosuid, suid, dev, nodev, exec, noexec, sync, async, atime, noatime, diratime, nodiratime, loud, bind, move, shared, slave, private, unbindable, rshared, rslave, rprivate, and runbindable. config BUSYBOX_CONFIG_FEATURE_MOUNT_FSTAB depends on BUSYBOX_CONFIG_MOUNT bool "Support /etc/fstab and -a (mount all)" default BUSYBOX_DEFAULT_FEATURE_MOUNT_FSTAB help Support mount all and looking for files in /etc/fstab. config BUSYBOX_CONFIG_FEATURE_MOUNT_OTHERTAB depends on BUSYBOX_CONFIG_FEATURE_MOUNT_FSTAB bool "Support -T " default BUSYBOX_DEFAULT_FEATURE_MOUNT_OTHERTAB help Support mount -T (specifying an alternate fstab) config BUSYBOX_CONFIG_MOUNTPOINT bool "mountpoint (4.9 kb)" default BUSYBOX_DEFAULT_MOUNTPOINT help mountpoint checks if the directory is a mountpoint. config BUSYBOX_CONFIG_NOLOGIN bool "nologin" default BUSYBOX_DEFAULT_NOLOGIN depends on BUSYBOX_CONFIG_FEATURE_SH_EMBEDDED_SCRIPTS help Politely refuse a login config BUSYBOX_CONFIG_NOLOGIN_DEPENDENCIES bool "Enable dependencies for nologin" default BUSYBOX_DEFAULT_NOLOGIN_DEPENDENCIES # Y default makes it harder to select single-applet test depends on BUSYBOX_CONFIG_NOLOGIN select BUSYBOX_CONFIG_CAT select BUSYBOX_CONFIG_ECHO select BUSYBOX_CONFIG_SLEEP help nologin is implemented as a shell script. It requires the following in the runtime environment: cat echo sleep If you know these will be available externally you can disable this option. config BUSYBOX_CONFIG_NSENTER bool "nsenter (6.5 kb)" default BUSYBOX_DEFAULT_NSENTER help Run program with namespaces of other processes. config BUSYBOX_CONFIG_PIVOT_ROOT bool "pivot_root (1.1 kb)" default BUSYBOX_DEFAULT_PIVOT_ROOT 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 (5.6 kb)" default BUSYBOX_DEFAULT_RDATE 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_RDEV bool "rdev (1.8 kb)" default BUSYBOX_DEFAULT_RDEV help Print the device node associated with the filesystem mounted at '/'. config BUSYBOX_CONFIG_READPROFILE bool "readprofile (7.1 kb)" default BUSYBOX_DEFAULT_READPROFILE help This allows you to parse /proc/profile for basic profiling. config BUSYBOX_CONFIG_RENICE bool "renice (4.2 kb)" default BUSYBOX_DEFAULT_RENICE help Renice alters the scheduling priority of one or more running processes. config BUSYBOX_CONFIG_REV bool "rev (4.4 kb)" default BUSYBOX_DEFAULT_REV help Reverse lines of a file or files. config BUSYBOX_CONFIG_RTCWAKE bool "rtcwake (6.8 kb)" default BUSYBOX_DEFAULT_RTCWAKE help Enter a system sleep state until specified wakeup time. config BUSYBOX_CONFIG_SCRIPT bool "script (8.6 kb)" default BUSYBOX_DEFAULT_SCRIPT help The script makes typescript of terminal session. config BUSYBOX_CONFIG_SCRIPTREPLAY bool "scriptreplay (2.4 kb)" default BUSYBOX_DEFAULT_SCRIPTREPLAY help This program replays a typescript, using timing information given by script -t. config BUSYBOX_CONFIG_SETARCH bool "setarch (3.6 kb)" default BUSYBOX_DEFAULT_SETARCH 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_LINUX32 bool "linux32 (3.3 kb)" default BUSYBOX_DEFAULT_LINUX32 help Alias to "setarch linux32". config BUSYBOX_CONFIG_LINUX64 bool "linux64 (3.3 kb)" default BUSYBOX_DEFAULT_LINUX64 help Alias to "setarch linux64". config BUSYBOX_CONFIG_SETPRIV bool "setpriv (6.6 kb)" default BUSYBOX_DEFAULT_SETPRIV select BUSYBOX_CONFIG_LONG_OPTS help Run a program with different Linux privilege settings. Requires kernel >= 3.5 config BUSYBOX_CONFIG_FEATURE_SETPRIV_DUMP bool "Support dumping current privilege state" default BUSYBOX_DEFAULT_FEATURE_SETPRIV_DUMP depends on BUSYBOX_CONFIG_SETPRIV help Enables the "--dump" switch to print out the current privilege state. This is helpful for diagnosing problems. config BUSYBOX_CONFIG_FEATURE_SETPRIV_CAPABILITIES bool "Support capabilities" default BUSYBOX_DEFAULT_FEATURE_SETPRIV_CAPABILITIES depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_SETPRIV_CAPABILITY_NAMES bool "Support capability names" default BUSYBOX_DEFAULT_FEATURE_SETPRIV_CAPABILITY_NAMES depends on BUSYBOX_CONFIG_SETPRIV && BUSYBOX_CONFIG_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_CONFIG_SETSID bool "setsid (3.6 kb)" default BUSYBOX_DEFAULT_SETSID help setsid runs a program in a new session config BUSYBOX_CONFIG_SWAPON bool "swapon (15 kb)" default BUSYBOX_DEFAULT_SWAPON 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_CONFIG_FEATURE_SWAPON_DISCARD bool "Support discard option -d" default BUSYBOX_DEFAULT_FEATURE_SWAPON_DISCARD depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_SWAPON_PRI bool "Support priority option -p" default BUSYBOX_DEFAULT_FEATURE_SWAPON_PRI depends on BUSYBOX_CONFIG_SWAPON help Enable support for setting swap device priority in swapon. config BUSYBOX_CONFIG_SWAPOFF bool "swapoff (14 kb)" default BUSYBOX_DEFAULT_SWAPOFF config BUSYBOX_CONFIG_FEATURE_SWAPONOFF_LABEL bool "Support specifying devices by label or UUID" default BUSYBOX_DEFAULT_FEATURE_SWAPONOFF_LABEL depends on BUSYBOX_CONFIG_SWAPON || BUSYBOX_CONFIG_SWAPOFF select BUSYBOX_CONFIG_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_CONFIG_SWITCH_ROOT bool "switch_root (5.5 kb)" default BUSYBOX_DEFAULT_SWITCH_ROOT 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_TASKSET bool "taskset (4.2 kb)" default BUSYBOX_DEFAULT_TASKSET help Retrieve or set a processes's CPU affinity. This requires sched_{g,s}etaffinity support in your libc. config BUSYBOX_CONFIG_FEATURE_TASKSET_FANCY bool "Fancy output" default BUSYBOX_DEFAULT_FEATURE_TASKSET_FANCY depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_TASKSET_CPULIST bool "CPU list support (-c option)" default BUSYBOX_DEFAULT_FEATURE_TASKSET_CPULIST depends on BUSYBOX_CONFIG_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_CONFIG_UEVENT bool "uevent (3.1 kb)" default BUSYBOX_DEFAULT_UEVENT help uevent is a netlink listener for kernel uevent notifications sent via netlink. It is usually used for dynamic device creation. config BUSYBOX_CONFIG_UMOUNT bool "umount (5.1 kb)" default BUSYBOX_DEFAULT_UMOUNT 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 "Support -a (unmount all)" default BUSYBOX_DEFAULT_FEATURE_UMOUNT_ALL depends on BUSYBOX_CONFIG_UMOUNT help Support -a option to unmount all currently mounted filesystems. config BUSYBOX_CONFIG_UNSHARE bool "unshare (7.2 kb)" default BUSYBOX_DEFAULT_UNSHARE depends on !BUSYBOX_CONFIG_NOMMU select BUSYBOX_CONFIG_LONG_OPTS help Run program with some namespaces unshared from parent. config BUSYBOX_CONFIG_WALL bool "wall (2.6 kb)" default BUSYBOX_DEFAULT_WALL depends on BUSYBOX_CONFIG_FEATURE_UTMP help Write a message to all users that are logged in. 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 BUSYBOX_DEFAULT_FEATURE_MOUNT_LOOP 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_MOUNT_LOOP_CREATE bool "Create new loopback devices if needed" default BUSYBOX_DEFAULT_FEATURE_MOUNT_LOOP_CREATE depends on BUSYBOX_CONFIG_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_CONFIG_FEATURE_MTAB_SUPPORT bool "Support old /etc/mtab file" 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. source "volume_id/Config.in" endmenu
