- 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.
+ sys_sysctl uses binary paths that have been found challenging
+ to properly maintain and use. The interface in /proc/sys
+ using paths with ascii names is now the primary path to this

+ Almost nothing using the binary sysctl interface so if you are
+ trying to save some space it is probably safe to disable this,
+ making your kernel marginally smaller.
