-config SYSCTL
- bool "Sysctl support" if EMBEDDED
- default y
- ---help---
- 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.

+ Enable the deprecated sysctl system call. sys_sysctl uses

+ 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.
+
+ Unless you have an application that uses the sys_sysctl interface
+ you should probably say N here.
