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 going away in a future release.
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",

81 config CONFIG_DEVFSD_MODLOAD
82 bool "Adds support for MODLOAD keyword in devsfd.conf"

104 config CONFIG_FEATURE_DEVFS
105 bool " Use devfs names for all devices (obsolete)"
108 This tells busybox to look for names like /dev/loop/0 instead of
109 /dev/loop0. If your /dev directory has normal names instead of
110 devfs names, you don't want this.
112 This is obsolete and will be going away someday. Consider it

151 The -m flag enables a simpler status line with a percentage.
153 config CONFIG_FEATURE_LESS_FLAGCS
154 bool "Enable flag changes"
156 depends on CONFIG_LESS

183 config CONFIG_FEATURE_HDPARM_GET_IDENTITY
184 bool "Support obtaining detailed information directly from drives"
186 depends on CONFIG_HDPARM
188 Enables the -I and -i options to obtain detailed information
189 directly from drives about their capabilities and supported ATA
190 feature set. If no device name is specified, hdparm will read
191 identify data from stdin. Enabling this option will add about 16k...

194 bool "Register an IDE interface (DANGEROUS)"
196 depends on CONFIG_HDPARM
198 Enables the 'hdparm -R' option to register an IDE interface.
199 This is dangerous stuff, so you should probably say N.
201 config CONFIG_FEATURE_HDPARM_HDIO_UNREGISTER_HWIF
202 bool "Un-register an IDE interface (DANGEROUS)"
204 depends on CONFIG_HDPARM
206 Enables the 'hdparm -U' option to un-register an IDE interface.
207 This is dangerous stuff, so you should probably say N.
209 config CONFIG_FEATURE_HDPARM_HDIO_DRIVE_RESET
210 bool "perform device reset (DANGEROUS)"
212 depends on CONFIG_HDPARM

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

227 bool "get/set using_dma flag (DANGEROUS)"
229 depends on CONFIG_HDPARM
231 Enables the 'hdparm -d' option to get/set using_dma flag.

234 config CONFIG_MAKEDEVS
238 'makedevs' is a utility used to create a batch of devices with
241 There are two choices for command line behaviour, the interface
242 as used by LEAF/Linux Router Project, or a device table file.
244 'leaf' is traditionally what busybox follows, it allows multiple
245 devices of a particluar type to be created per command.
247 Device properties are passed as command line arguments.
249 'table' reads device properties from a file or stdin, allowing
250 a batch of unrelated devices to be made with one command.
251 User/group names are allowed as an alternative to uid/gid.

277 to advance or rewind a tape past a specified number of archive
280 config CONFIG_RUNLEVEL
284 find the current and previous system runlevel.
286 This applet uses utmp but does not rely on busybox supporing
287 utmp on purpose. It is used by e.g. emdebian via /etc/init.d/rc.

314 config CONFIG_TASKSET
318 Retrieve or set a processes's CPU affinity (on linux)
324 The time command runs the specified program with the given arguments.
325 When the command finishes, time writes a message to standard output
326 giving timing statistics about this program run.
328 config CONFIG_WATCHDOG
332 The watchdog utility is used with hardware or software watchdog
333 device drivers. It opens the specified watchdog device special file
334 and periodically writes a magic character to the device. If the
335 watchdog applet ever fails to write the magic character within a
336 certain amount of time, the watchdog device assumes the system has
337 hung, and will cause the hardware to reboot.
