| config CONFIG_DMESG |
| bool "dmesg" |
| default n |
| 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 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 CONFIG_FEATURE_FBSET_FANCY |
| bool " Turn on extra fbset options" |
| default n |
| depends on 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 CONFIG_FEATURE_FBSET_READMODE |
| bool " Turn on fbset readmode support" |
| default n |
| depends on CONFIG_FBSET |
| help |
| This option allows fbset to read the video mode database stored by |
| default as /etc/fb.modes, which can be used to set frame buffer |
| device to pre-defined video modes. |
| |
| config 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 CONFIG_FDFORMAT |
| bool "fdformat" |
| default n |
| help |
| fdformat is used to low-level format a floppy disk. |
| |
| config 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 FDISK_SUPPORT_LARGE_DISKS |
| bool " support over 4GB disks" |
| default y |
| depends on CONFIG_FDISK |
| help |
| Enable this option to support large disks > 4GB. |
| |
| config CONFIG_FEATURE_FDISK_WRITABLE |
| bool " Write support" |
| default y |
| depends on 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 CONFIG_FEATURE_AIX_LABEL |
| bool " Support AIX disklabels" |
| default n |
| depends on CONFIG_FDISK && 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 CONFIG_FEATURE_SGI_LABEL |
| bool " Support SGI disklabels" |
| default n |
| depends on CONFIG_FDISK && 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 CONFIG_FEATURE_SUN_LABEL |
| bool " Support SUN disklabels" |
| default n |
| depends on CONFIG_FDISK && 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 CONFIG_FEATURE_OSF_LABEL |
| bool " Support BSD disklabels" |
| default n |
| depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE |
| help |
| Enabling this option allows you to create or change BSD disklabels |
| and define and edit BSD disk slices. |
| |
| config CONFIG_FEATURE_FDISK_ADVANCED |
| bool " Support expert mode" |
| default n |
| depends on CONFIG_FDISK && 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 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 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 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 wish to be able to create minix filesystems |
| this utility will do the job for you. |
| |
| comment "Minix filesystem support" |
| depends on CONFIG_FSCK_MINIX || CONFIG_MKFS_MINIX |
| |
| config CONFIG_FEATURE_MINIX2 |
| bool " Support Minix fs v2 (fsck_minix/mkfs_minix)" |
| default y |
| depends on CONFIG_FSCK_MINIX || 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 CONFIG_GETOPT |
| bool "getopt" |
| default n |
| 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 CONFIG_HEXDUMP |
| bool "hexdump" |
| default n |
| 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 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 CONFIG_FEATURE_HWCLOCK_LONGOPTIONS |
| bool " Support long options (--hctosys,...)" |
| default n |
| depends on CONFIG_HWCLOCK |
| 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 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 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 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 CONFIG_FEATURE_USE_TERMIOS |
| bool " Use termios to manipulate the screen" |
| default y |
| depends on 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 CONFIG_PIVOT_ROOT |
| bool "pivot_root" |
| default n |
| 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'. |
| |
| config CONFIG_RDATE |
| bool "rdate" |
| default n |
| 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 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 CONFIG_MOUNT |
| bool "mount" |
| default n |
| 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 CONFIG_NFSMOUNT |
| bool " Support mounting NFS file systems" |
| default n |
| depends on CONFIG_MOUNT |
| help |
| Enable mounting of NFS file systems. |
| |
| config CONFIG_UMOUNT |
| bool "umount" |
| default n |
| 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 CONFIG_FEATURE_MOUNT_FORCE |
| bool " Support forced filesystem unmounting" |
| default n |
| depends on CONFIG_UMOUNT |
| help |
| This allows you to _force_ a filesystem to be umounted. This is generally |
| only useful when you want to get rid of an unreachable NFS system. |
| |
| comment "Common options for mount/umount" |
| depends on CONFIG_MOUNT || CONFIG_UMOUNT |
| |
| config CONFIG_FEATURE_MOUNT_LOOP |
| bool " Support for loop devices" |
| default n |
| depends on CONFIG_MOUNT || CONFIG_UMOUNT |
| help |
| Enabling this feature allows mount to use the '-o' loop options, |
| which lets you loop mount files. Mount will automagically setup and |
| free the necessary loop devices so you do not need to mess with the |
| 'losetup' utility unless you really want to. This is really |
| only useful if you plan to loop mount files. |
| |
| config CONFIG_FEATURE_MTAB_SUPPORT |
| bool " Support for a real /etc/mtab (instead of /proc/mounts)" |
| default n |
| depends on CONFIG_MOUNT || CONFIG_UMOUNT |
| help |
| If your root filesystem is writable and you wish to have the 'mount' |
| utility create an mtab file listing the filesystems which have been |
| mounted then you should enable this option. Most people that use |
| BusyBox have a read-only root filesystem, so they will leave this |
| option disabled and BusyBox will use the /proc/mounts file. |
| |
| config CONFIG_FEATURE_MTAB_FILENAME |
| string " mtab file location" |
| default "/etc/mtab" |
| depends on CONFIG_FEATURE_MTAB_SUPPORT |
| help |
| Some people have a read only root filesystem, but they also wish to |
| have the 'mount' utility create an mtab file listing the filesystems |
| which have been mounted. This option allows you to specify an alternative |
| location for the mtab file, such as /var/mtab, or /tmp/mtab. The default |
| value is /etc/mtab, which is where this file is located on most desktop |
| Linux systems. |
