-What: sys_sysctl
-When: January 2007
-Why: The same information is available through /proc/sys and that is the
- interface user space prefers to use. And there do not appear to be
- any existing user in user space of sys_sysctl. The additional
- maintenance overhead of keeping a set of binary names gets
- in the way of doing a good job of maintaining this interface.

---help---
- Enable the deprecated sysctl system call. sys_sysctl uses
- binary paths that have been found to be a major pain to maintain
- and use. The interface in /proc/sys is now the primary and what
- everyone 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.
+ This option allows you to specify whether or not to build into
+ your kernel support for the sysctl system call. You can disable
+ this if you are building a kernel for a system with limited
+ resources (e.g. an embedded device) and your kernel image will
+ shrink by a few kilobytes.
+
+ NOTE: Disabling this option will cause a warning to be printed
+ if a program attempts to use this system call.
- Unless you have an application that uses the sys_sysctl interface
- you should probably say N here.
+ If you are sure your userspace enviroment has no need for this
+ system call you can say N here.
