+         The sysctl interface provides a means of dynamically changing
+         certain kernel parameters and variables on the fly without requiring
+         a recompile of the kernel or reboot of the system.  The primary
+         interface is through /proc/sys.  If you say Y here a tree of
+         modifiable sysctl entries will be generated beneath the
+          /proc/sys directory. They are explained in the files
+         in <file:Documentation/sysctl/>.  Note that enabling this
+         option will enlarge the kernel by at least 8 KB.
+
+         As it is generally a good thing, you should say Y here unless
+         building a kernel for install/rescue disks or your system is very
+         limited in memory.
