9 | config CONFIG_DMESG | ||
10 | bool "dmesg" | ||
11 | default n | ||
12 | help | ||
13 | dmesg is used to examine or control the kernel ring buffer. When the | ||
14 | Linux kernel prints messages to the system log, they are stored in | ||
15 | the kernel ring buffer. You can use dmesg to print the kernel's ring | ||
16 | buffer, clear the kernel ring buffer, change the size of the kernel | ||
17 | ring buffer, and change the priority level at which kernel messages | ||
18 | are also logged to the system console. Enable this option if you | ||
19 | wish to enable the 'dmesg' utility. | ||
20 | |||
21 | config CONFIG_FBSET | ||
22 | bool "fbset" | ||
23 | default n | ||
24 | help | ||
25 | fbset is used to show or change the settings of a Linux frame buffer | ||
26 | device. The frame buffer device provides a simple and unique | ||
27 | interface to access a graphics display. Enable this option | ||
28 | if you wish to enable the 'fbset' utility. | ||
29 | |||
30 | |||
31 | config CONFIG_FEATURE_FBSET_FANCY | ||
32 | bool " Turn on extra fbset options" | ||
33 | default n | ||
34 | depends on CONFIG_FBSET | ||
35 | help | ||
36 | This option enables extended fbset options, allowing one to set the | ||
37 | framebuffer size, color depth, etc. interface to access a graphics | ||
38 | display. Enable this option if you wish to enable extended fbset | ||
39 | options. | ||
40 | |||
41 | config CONFIG_FEATURE_FBSET_READMODE | ||
42 | bool " Turn on fbset readmode support" | ||
43 | default n | ||
44 | depends on CONFIG_FBSET | ||
45 | help | ||
46 | This option allows fbset to read the video mode database stored by | ||
47 | default as /etc/fb.modes, which can be used to set frame buffer | ||
48 | device to pre-defined video modes. | ||
49 | |||
50 | config CONFIG_FDFLUSH | ||
51 | bool "fdflush" | ||
52 | default n | ||
53 | help | ||
54 | fdflush is only needed when changing media on slightly-broken | ||
55 | removable media drives. It is used to make Linux believe that a | ||
56 | hardware disk-change switch has been actuated, which causes Linux to | ||
57 | forget anything it has cached from the previous media. If you have | ||
58 | such a slightly-broken drive, you will need to run fdflush every time | ||
59 | you change a disk. Most people have working hardware and can safely | ||
60 | leave this disabled. | ||
61 | |||
62 | config CONFIG_FDFORMAT | ||
63 | bool "fdformat" | ||
64 | default n | ||
65 | help | ||
66 | fdformat is used to low-level format a floppy disk. | ||
67 | |||
68 | config CONFIG_FDISK | ||
69 | bool "fdisk" | ||
70 | default n | ||
71 | help | ||
72 | The fdisk utility is used to divide hard disks into one or more | ||
73 | logical disks, which are generally called partitions. This utility | ||
74 | can be used to list and edit the set of partitions or BSD style | ||
75 | 'disk slices' that are defined on a hard drive. | ||
76 | |||
77 | config FDISK_SUPPORT_LARGE_DISKS | ||
78 | bool " support over 4GB disks" | ||

82 | Enable this option to support large disks > 4GB. | ||
83 | |||
84 | config CONFIG_FEATURE_FDISK_WRITABLE | ||
85 | bool " Write support" | ||
86 | default y | ||
87 | depends on CONFIG_FDISK | ||
88 | help | ||
89 | Enabling this option allows you to create or change a partition table | ||
90 | and write those changes out to disk. If you leave this option | ||
91 | disabled, you will only be able to view the partition table. | ||
92 | |||
93 | config CONFIG_FEATURE_AIX_LABEL | ||
94 | bool " Support AIX disklabels" | ||
95 | default n | ||
96 | depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE | ||
97 | help | ||
98 | Enabling this option allows you to create or change AIX disklabels. | ||
99 | Most people can safely leave this option disabled. | ||
100 | |||
101 | config CONFIG_FEATURE_SGI_LABEL | ||
102 | bool " Support SGI disklabels" | ||
103 | default n | ||
104 | depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE | ||
105 | help | ||
106 | Enabling this option allows you to create or change SGI disklabels. | ||
107 | Most people can safely leave this option disabled. | ||
108 | |||
109 | config CONFIG_FEATURE_SUN_LABEL | ||
110 | bool " Support SUN disklabels" | ||
111 | default n | ||
112 | depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE | ||
113 | help | ||
114 | Enabling this option allows you to create or change SUN disklabels. | ||
115 | Most people can safely leave this option disabled. | ||
116 | |||
117 | config CONFIG_FEATURE_OSF_LABEL | ||
118 | bool " Support BSD disklabels" | ||
119 | default n | ||
120 | depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE | ||
121 | help | ||
122 | Enabling this option allows you to create or change BSD disklabels | ||

126 | bool " Support expert mode" | ||
127 | default n | ||
128 | depends on CONFIG_FDISK && CONFIG_FEATURE_FDISK_WRITABLE | ||
129 | help | ||
130 | Enabling this option allows you to do terribly unsafe things like | ||
131 | define arbitrary drive geometry, move the beginning of data in a | ||
132 | partition, and similarly evil things. Unless you have a very good | ||
133 | reason you would be wise to leave this disabled. | ||
134 | |||
135 | config CONFIG_FREERAMDISK | ||
136 | bool "freeramdisk" | ||
137 | default n | ||
138 | help | ||
139 | Linux allows you to create ramdisks. This utility allows you to | ||
140 | delete them and completely free all memory that was used for the | ||
141 | ramdisk. For example, if you boot Linux into a ramdisk and later | ||
142 | pivot_root, you may want to free the memory that is allocated to the | ||
143 | ramdisk. If you have no use for freeing memory from a ramdisk, leave | ||
144 | this disabled. | ||
145 | |||
146 | config CONFIG_FSCK_MINIX | ||
147 | bool "fsck_minix" | ||
148 | default n | ||
149 | help | ||
150 | The minix filesystem is a nice, small, compact, read-write filesystem | ||
151 | with little overhead. It is not a journaling filesystem however and | ||
152 | can experience corruption if it is not properly unmounted or if the | ||
153 | power goes off in the middle of a write. This utility allows you to | ||
154 | check for and attempt to repair any corruption that occurs to a minix | ||
155 | filesystem. | ||
156 | |||
157 | config CONFIG_MKFS_MINIX | ||
158 | bool "mkfs_minix" | ||
159 | default n | ||
160 | help | ||
161 | The minix filesystem is a nice, small, compact, read-write filesystem | ||
162 | with little overhead. If you wish to be able to create minix filesystems | ||
163 | this utility will do the job for you. | ||
164 | |||
165 | comment "Minix filesystem support" | ||
166 | depends on CONFIG_FSCK_MINIX || CONFIG_MKFS_MINIX | ||

169 | bool " Support Minix fs v2 (fsck_minix/mkfs_minix)" | ||
170 | default y | ||
171 | depends on CONFIG_FSCK_MINIX || CONFIG_MKFS_MINIX | ||
172 | help | ||
173 | If you wish to be able to create version 2 minix filesystems, enable this. | ||
174 | If you enabled 'mkfs_minix' then you almost certainly want to be using the | ||
175 | version 2 filesystem support. | ||
176 | |||
177 | config CONFIG_GETOPT | ||
178 | bool "getopt" | ||
179 | default n | ||
180 | help | ||
181 | The getopt utility is used to break up (parse) options in command | ||
182 | lines to make it easy to write complex shell scripts that also check | ||
183 | for legal (and illegal) options. If you want to write horribly | ||
184 | complex shell scripts, or use some horribly complex shell script | ||
185 | written by others, this utility may be for you. Most people will | ||
186 | wisely leave this disabled. | ||
187 | |||
188 | config CONFIG_HEXDUMP | ||
189 | bool "hexdump" | ||
190 | default n | ||
191 | help | ||
192 | The hexdump utility is used to display binary data in a readable | ||
193 | way that is comparable to the output from most hex editors. | ||
194 | |||
195 | config CONFIG_HWCLOCK | ||
196 | bool "hwclock" | ||
197 | default n | ||
198 | help | ||
199 | The hwclock utility is used to read and set the hardware clock | ||
200 | on a system. This is primarily used to set the current time on | ||
201 | shutdown in the hardware clock, so the hardware will keep the | ||
202 | correct time when Linux is _not_ running. | ||
203 | |||
204 | config CONFIG_FEATURE_HWCLOCK_LONGOPTIONS | ||
205 | bool " Support long options (--hctosys,...)" | ||
206 | default n | ||
207 | depends on CONFIG_HWCLOCK | ||
208 | help | ||
209 | By default, the hwclock utility only uses short options. If you | ||
210 | are overly fond of its long options, such as --hctosys, --utc, etc) | ||
211 | then enable this option. | ||
212 | |||
213 | config CONFIG_LOSETUP | ||
214 | bool "losetup" | ||
215 | default n | ||
216 | help | ||
217 | losetup is used to associate or detach a loop device with a regular | ||
218 | file or block device, and to query the status of a loop device. This | ||
219 | version does not currently support enabling data encryption. | ||
220 | |||
221 | config CONFIG_MKSWAP | ||
222 | bool "mkswap" | ||
223 | default n | ||
224 | help | ||
225 | The mkswap utility is used to configure a file or disk partition as | ||
226 | Linux swap space. This allows Linux to use the entire file or | ||
227 | partition as if it were additional RAM, which can greatly increase | ||
228 | the capability of low-memory machines. This additional memory is | ||
229 | much slower than real RAM, but can be very helpful at preventing your | ||
230 | applications being killed by the Linux out of memory (OOM) killer. | ||
231 | Once you have created swap space using 'mkswap' you need to enable | ||
232 | the swap space using the 'swapon' utility. | ||
233 | |||
234 | config CONFIG_MORE | ||
235 | bool "more" | ||
236 | default n | ||
237 | help | ||
238 | more is a simple utility which allows you to read text one screen | ||
239 | sized page at a time. If you want to read text that is larger than | ||
240 | the screen, and you are using anything faster than a 300 baud modem, | ||
241 | you will probably find this utility very helpful. If you don't have | ||
242 | any need to reading text files, you can leave this disabled. | ||
243 | |||
244 | config CONFIG_FEATURE_USE_TERMIOS | ||
245 | bool " Use termios to manipulate the screen" | ||
246 | default y | ||
247 | depends on CONFIG_MORE | ||
248 | help | ||
249 | This option allows utilities such as 'more' and 'top' to determine | ||
250 | the size of the screen. If you leave this disabled, your utilities | ||
251 | that display things on the screen will be especially primitive and | ||
252 | will be unable to determine the current screen size, and will be | ||
253 | unable to move the cursor. | ||
254 | |||
255 | config CONFIG_PIVOT_ROOT | ||
256 | bool "pivot_root" | ||
257 | default n | ||
258 | help | ||
259 | The pivot_root utility swaps the mount points for the root filesystem | ||
260 | with some other mounted filesystem. This allows you to do all sorts | ||
261 | of wild and crazy things with your Linux system and is far more | ||
262 | powerful than 'chroot'. | ||
263 | |||
264 | config CONFIG_RDATE | ||
265 | bool "rdate" | ||
266 | default n | ||
267 | help | ||
268 | The rdate utility allows you to synchronize the date and time of your | ||
269 | system clock with the date and time of a remote networked system using | ||
270 | the RFC868 protocol, which is built into the inetd daemon on most | ||
271 | systems. | ||
272 | |||
273 | config CONFIG_SWAPONOFF | ||
274 | bool "swaponoff" | ||
275 | default n | ||
276 | help | ||
277 | This option enables both the 'swapon' and the 'swapoff' utilities. | ||
278 | Once you have created some swap space using 'mkswap', you also need | ||
279 | to enable your swap space with the 'swapon' utility. The 'swapoff' | ||
280 | utility is used, typically at system shutdown, to disable any swap | ||
281 | space. If you are not using any swap space, you can leave this | ||
282 | option disabled. | ||
283 | |||
284 | config CONFIG_MOUNT | ||
285 | bool "mount" | ||
286 | default n | ||
287 | help | ||
288 | All files and filesystems in Unix are arranged into one big directory | ||
289 | tree. The 'mount' utility is used to graft a filesystem onto a | ||
290 | particular part of the tree. A filesystem can either live on a block | ||
291 | device, or it can be accessible over the network, as is the case with | ||
292 | NFS filesystems. Most people using BusyBox will also want to enable | ||
293 | the 'mount' utility. | ||
294 | |||
295 | config CONFIG_NFSMOUNT | ||
296 | bool " Support mounting NFS file systems" | ||
297 | default n | ||
298 | depends on CONFIG_MOUNT | ||
299 | help | ||
300 | Enable mounting of NFS file systems. | ||
301 | |||
302 | config CONFIG_UMOUNT | ||
303 | bool "umount" | ||
304 | default n | ||
305 | help | ||
306 | When you want to remove a mounted filesystem from its current mount point, | ||
307 | for example when you are shutting down the system, the 'umount' utility is | ||
308 | the tool to use. If you enabled the 'mount' utility, you almost certainly | ||
309 | also want to enable 'umount'. | ||
310 | |||
311 | config CONFIG_FEATURE_MOUNT_FORCE | ||
312 | bool " Support forced filesystem unmounting" | ||
313 | default n | ||
314 | depends on CONFIG_UMOUNT | ||
315 | help | ||
316 | This allows you to _force_ a filesystem to be umounted. This is generally | ||
317 | only useful when you want to get rid of an unreachable NFS system. | ||

323 | bool " Support for loop devices" | ||
324 | default n | ||
325 | depends on CONFIG_MOUNT || CONFIG_UMOUNT | ||
326 | help | ||
327 | Enabling this feature allows mount to use the '-o' loop options, | ||
328 | which lets you loop mount files. Mount will automagically setup and | ||
329 | free the necessary loop devices so you do not need to mess with the | ||
330 | 'losetup' utility unless you really want to. This is really | ||
331 | only useful if you plan to loop mount files. | ||

337 | help | ||
338 | If your root filesystem is writable and you wish to have the 'mount' | ||
339 | utility create an mtab file listing the filesystems which have been | ||
340 | mounted then you should enable this option. Most people that use | ||
341 | BusyBox have a read-only root filesystem, so they will leave this | ||
342 | option disabled and BusyBox will use the /proc/mounts file. | ||
343 | |||

348 | help | ||
349 | Some people have a read only root filesystem, but they also wish to | ||
350 | have the 'mount' utility create an mtab file listing the filesystems | ||
351 | which have been mounted. This option allows you to specify an alternative | ||
352 | location for the mtab file, such as /var/mtab, or /tmp/mtab. The default | ||
353 | value is /etc/mtab, which is where this file is located on most desktop | ||
