+Documentation for /proc/sys/ kernel version 2.2.10
+ (c) 1998, 1999, Rik van Riel <riel@nl.linux.org>
+'Why', I hear you ask, 'would anyone even _want_ documentation
+for them sysctl files? If anybody really needs it, it's all in
+the source...'
+Well, this documentation is written because some people either
+don't know they need to tweak something, or because they don't
+have the time or knowledge to read the source code.
+Furthermore, the programmers who built sysctl have built it to
+be actually used, not just for the fun of programming it :-)
+Legal blurb:
+As usual, there are two main things to consider:
+1. you get what you pay for
+2. it's free
+The consequences are that I won't guarantee the correctness of
+this document, and if you come to me complaining about how you
+screwed up your system because of wrong documentation, I won't
+feel sorry for you. I might even laugh at you...
+But of course, if you _do_ manage to screw up your system using
+only the sysctl options used in this file, I'd like to hear of
+it. Not only to have a great laugh, but also to make sure that
+you're the last RTFMing person to screw up.
+In short, e-mail your suggestions, corrections and / or horror
+stories to: <riel@nl.linux.org>
+Rik van Riel.
+Sysctl is a means of configuring certain aspects of the kernel
+at run-time, and the /proc/sys/ directory is there so that you
+don't even need special tools to do it!
+In fact, there are only four things needed to use these config
+- a running Linux system
+- root access
+- common sense (this is especially hard to come by these days)
+- knowledge of what all those values mean
+As a quick 'ls /proc/sys' will show, the directory consists of
+several (arch-dependent?) subdirs. Each subdir is mainly about
+one part of the kernel, so you can do configuration on a piece
+by piece basis, or just some 'thematic frobbing'.
+The subdirs are about:
+abi/ execution domains & personalities
+debug/ <empty>
+dev/ device specific information (eg dev/cdrom/info)
+fs/ specific filesystems
+ filehandle, inode, dentry and quota tuning
+ binfmt_misc <Documentation/binfmt_misc.txt>
+kernel/ global kernel info / tuning
+ miscellaneous stuff
+net/ networking stuff, for documentation look in:
+ <Documentation/networking/>
+proc/ <empty>
+sunrpc/ SUN Remote Procedure Call (NFS)
+vm/ memory management tuning
+ buffer and cache management
+These are the subdirs I have on my system. There might be more
+or other subdirs in another setup. If you see another dir, I'd
+really like to hear about it :-)
