+	  This option creates deprecated symlinks such as the
+	  "device"-link, the <subsystem>:<name>-link, and the
+	  "bus"-link. It may also add deprecated key in the
+	  uevent environment.
+	  None of these features or values should be used today, as
+	  they export driver core implementation details to userspace
+	  or export properties which can't be kept stable across kernel
+	  releases.
+
+	  If enabled, this option will also move any device structures
+	  that belong to a class, back into the /sys/class heirachy, in
+	  order to support older versions of udev.
+
+	  If you are using a distro that was released in 2006 or later,
+	  it should be safe to say N here.

-	  Enable the deprecated sysctl system call.  sys_sysctl uses
-	  binary paths that have been found to be a major pain to maintain

-	  Nothing has been using the binary sysctl interface for some
-	  time now so nothing should break if you disable sysctl syscall
-	  support, and your kernel will get marginally smaller.
+	  Almost nothing using the binary sysctl interface so if you are
+	  trying to save some space it is probably safe to disable this,
