+config BUSYBOX_CONFIG_SYSLOGD
+	bool "syslogd"
+	default BUSYBOX_DEFAULT_SYSLOGD
+	help
+	  The syslogd utility is used to record logs of all the
+	  significant events that occur on a system. Every
+	  message that is logged records the date and time of the
+	  event, and will generally also record the name of the
+	  application that generated the message. When used in
+	  conjunction with klogd, messages from the Linux kernel
+	  can also be recorded. This is terribly useful,
+	  especially for finding what happened when something goes
+	  wrong. And something almost always will go wrong if
+	  you wait long enough....
+
+config BUSYBOX_CONFIG_FEATURE_ROTATE_LOGFILE
+	bool "Rotate message files"
+	default BUSYBOX_DEFAULT_FEATURE_ROTATE_LOGFILE
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  This enables syslogd to rotate the message files
+	  on his own. No need to use an external rotatescript.
+
+config BUSYBOX_CONFIG_FEATURE_REMOTE_LOG
+	bool "Remote Log support"
+	default BUSYBOX_DEFAULT_FEATURE_REMOTE_LOG
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  When you enable this feature, the syslogd utility can
+	  be used to send system log messages to another system
+	  connected via a network. This allows the remote
+	  machine to log all the system messages, which can be
+	  terribly useful for reducing the number of serial
+	  cables you use. It can also be a very good security
+	  measure to prevent system logs from being tampered with
+	  by an intruder.
+
+config BUSYBOX_CONFIG_FEATURE_SYSLOGD_DUP
+	bool "Support -D (drop dups) option"
+	default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_DUP
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  Option -D instructs syslogd to drop consecutive messages
+	  which are totally the same.
+
+config BUSYBOX_CONFIG_FEATURE_SYSLOGD_CFG
+	bool "Support syslog.conf"
+	default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_CFG
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  Supports restricted syslogd config. See docs/syslog.conf.txt
+
+config BUSYBOX_CONFIG_FEATURE_SYSLOGD_READ_BUFFER_SIZE
+	int "Read buffer size in bytes"
+	default BUSYBOX_DEFAULT_FEATURE_SYSLOGD_READ_BUFFER_SIZE
+	range 256 20000
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  This option sets the size of the syslog read buffer.
+	  Actual memory usage increases around five times the
+	  change done here.
+
+config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
+	bool "Circular Buffer support"
+	default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG
+	depends on BUSYBOX_CONFIG_SYSLOGD
+	help
+	  When you enable this feature, the syslogd utility will
+	  use a circular buffer to record system log messages.
+	  When the buffer is filled it will continue to overwrite
+	  the oldest messages. This can be very useful for
+	  systems with little or no permanent storage, since
+	  otherwise system logs can eventually fill up your
+	  entire filesystem, which may cause your system to
+	  break badly.
+
+config BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG_BUFFER_SIZE
+	int "Circular buffer size in Kbytes (minimum 4KB)"
+	default BUSYBOX_DEFAULT_FEATURE_IPC_SYSLOG_BUFFER_SIZE
+	range 4 2147483647
+	depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
+	help
+	  This option sets the size of the circular buffer
+	  used to record system log messages.
+
+config BUSYBOX_CONFIG_LOGREAD
+	bool "logread"
+	default BUSYBOX_DEFAULT_LOGREAD
+	depends on BUSYBOX_CONFIG_FEATURE_IPC_SYSLOG
+	help
+	  If you enabled Circular Buffer support, you almost
+	  certainly want to enable this feature as well. This
+	  utility will allow you to read the messages that are
+	  stored in the syslogd circular buffer.
+
+config BUSYBOX_CONFIG_FEATURE_LOGREAD_REDUCED_LOCKING
+	bool "Double buffering"
+	default BUSYBOX_DEFAULT_FEATURE_LOGREAD_REDUCED_LOCKING
+	depends on BUSYBOX_CONFIG_LOGREAD
+	help
+	  'logread' ouput to slow serial terminals can have
+	  side effects on syslog because of the semaphore.
+	  This option make logread to double buffer copy
+	  from circular buffer, minimizing semaphore
+	  contention at some minor memory expense.
+
+config BUSYBOX_CONFIG_KLOGD
+	bool "klogd"
+	default BUSYBOX_DEFAULT_KLOGD
+	help
+	  klogd is a utility which intercepts and logs all
+	  messages from the Linux kernel and sends the messages
+	  out to the 'syslogd' utility so they can be logged. If
+	  you wish to record the messages produced by the kernel,
+	  you should enable this option.
+
+config BUSYBOX_CONFIG_FEATURE_KLOGD_KLOGCTL
+	bool "Use the klogctl() interface"
+	default BUSYBOX_DEFAULT_FEATURE_KLOGD_KLOGCTL
+	depends on BUSYBOX_CONFIG_KLOGD
+	select BUSYBOX_CONFIG_PLATFORM_LINUX
+	help
+	  The klogd applet supports two interfaces for reading
+	  kernel messages. Linux provides the klogctl() interface
+	  which allows reading messages from the kernel ring buffer
+	  independently from the file system.
+
+	  If you answer 'N' here, klogd will use the more portable
+	  approach of reading them from /proc or a device node.
+	  However, this method requires the file to be available.
+
+	  If in doubt, say 'Y'.
+
+config BUSYBOX_CONFIG_LOGGER
+	bool "logger"
+	default BUSYBOX_DEFAULT_LOGGER
+	select BUSYBOX_CONFIG_FEATURE_SYSLOG
+	help
+	    The logger utility allows you to send arbitrary text
+	    messages to the system log (i.e. the 'syslogd' utility) so
+	    they can be logged. This is generally used to help locate
+	    problems that occur within programs and scripts.
