27 Crond is a background daemon that parses individual crontab
28 files and executes commands on behalf of the users in question.
29 This is a port of dcron from slackware. It uses files of the
30 format /var/spool/cron/crontabs/<username> files, for example:
31 $ cat /var/spool/cron/crontabs/root
32 # Run daily cron jobs at 4:40 every day:

67 bool "devfsd (obsolete)"
70 This is deprecated, and will be removed at the end of 2008.
72 Provides compatibility with old device names on a devfs systems.
73 You should set it to true if you have devfs enabled.
74 The following keywords in devsfd.conf are supported:
75 "CLEAR_CONFIG", "INCLUDE", "OPTIONAL_INCLUDE", "RESTORE",
76 "PERMISSIONS", "EXECUTE", "COPY", "IGNORE",
77 "MKOLDCOMPAT", "MKNEWCOMPAT","RMOLDCOMPAT", "RMNEWCOMPAT".

108 This is obsolete and will be going away at the end of 2008..
110 This tells busybox to look for names like /dev/loop/0 instead of
111 /dev/loop0. If your /dev directory has normal names instead of
112 devfs names, you don't want this.
118 Used to eject cdroms. (defaults to /dev/cdrom)
123 select CONFIG_FEATURE_WTMP
125 'last' displays a list of the last users that logged into the system.
131 'less' is a pager, meaning that it displays text files. It possesses

140 brackets, facilitating programming.
142 config CONFIG_FEATURE_LESS_FLAGS
143 bool "Enable extra flags"
145 depends on CONFIG_LESS

150 The -m flag enables a simpler status line with a percentage.
152 config CONFIG_FEATURE_LESS_FLAGCS
153 bool "Enable flag changes"
155 depends on CONFIG_LESS
157 This enables the ability to change command-line flags within

182 config CONFIG_FEATURE_HDPARM_GET_IDENTITY
183 bool "Support obtaining detailed information directly from drives"
185 depends on CONFIG_HDPARM
187 Enables the -I and -i options to obtain detailed information
188 directly from drives about their capabilities and supported ATA
189 feature set. If no device name is specified, hdparm will read
190 identify data from stdin. Enabling this option will add about 16k...
192 config CONFIG_FEATURE_HDPARM_HDIO_SCAN_HWIF
193 bool "Register an IDE interface (DANGEROUS)"
195 depends on CONFIG_HDPARM
197 Enables the 'hdparm -R' option to register an IDE interface.
198 This is dangerous stuff, so you should probably say N.
200 config CONFIG_FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
201 bool "Un-register an IDE interface (DANGEROUS)"
203 depends on CONFIG_HDPARM
205 Enables the 'hdparm -U' option to un-register an IDE interface.
206 This is dangerous stuff, so you should probably say N.
208 config CONFIG_FEATURE_HDPARM_HDIO_DRIVE_RESET
209 bool "perform device reset (DANGEROUS)"
211 depends on CONFIG_HDPARM
213 Enables the 'hdparm -w' option to perform a device reset.

216 config CONFIG_FEATURE_HDPARM_HDIO_TRISTATE_HWIF
217 bool "tristate device for hotswap (DANGEROUS)"
219 depends on CONFIG_HDPARM
221 Enables the 'hdparm -x' option to tristate device for hotswap,
222 and the '-b' option to get/set bus state. This is dangerous
223 stuff, so you should probably say N.

226 bool "get/set using_dma flag (DANGEROUS)"
228 depends on CONFIG_HDPARM
230 Enables the 'hdparm -d' option to get/set using_dma flag.
231 This is dangerous stuff, so you should probably say N.
233 config CONFIG_MAKEDEVS
237 'makedevs' is a utility used to create a batch of devices with
240 There are two choices for command line behaviour, the interface
241 as used by LEAF/Linux Router Project, or a device table file.
243 'leaf' is traditionally what busybox follows, it allows multiple
244 devices of a particluar type to be created per command.
246 Device properties are passed as command line arguments.
248 'table' reads device properties from a file or stdin, allowing
249 a batch of unrelated devices to be made with one command.
250 User/group names are allowed as an alternative to uid/gid.

275 mt is used to control tape devices. You can use the mt utility
276 to advance or rewind a tape past a specified number of archive
279 config CONFIG_RUNLEVEL
283 find the current and previous system runlevel.
285 This applet uses utmp but does not rely on busybox supporing
286 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.
292 Receive files using the Xmodem protocol.
294 config CONFIG_STRINGS
298 strings prints the printable character sequences for each file
305 setsid runs a program in a new session
307 config CONFIG_TASKSET
311 Retrieve or set a processes's CPU affinity.
317 The time command runs the specified program with the given arguments.
318 When the command finishes, time writes a message to standard output
319 giving timing statistics about this program run.
321 config CONFIG_WATCHDOG
325 The watchdog utility is used with hardware or software watchdog
326 device drivers. It opens the specified watchdog device special file
327 and periodically writes a magic character to the device. If the
328 watchdog applet ever fails to write the magic character within a
329 certain amount of time, the watchdog device assumes the system has
330 hung, and will cause the hardware to reboot.
