-         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 consists of a system call, but if you say Y to "/proc
-         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.
-
-         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.
