-          a recompile of the kernel or reboot of the system.  The primary

-          file system support", 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.
