OK, if you're reading this, I assume you want to play with

This is not even remotely true. As shown above,
both code and data size are quite modest.

+
+How to report bugs
+
+If you have (or think you have) a bug with devfs, please follow the
+steps below:
+
+
+
+please make sure you have the latest devfs patches applied. The
+latest kernel version might not have the latest devfs patches applied
+yet (Linus is very busy)
+
+
+save a copy of your complete kernel logs (preferably by
+using the dmesg programme) for later inclusion in your bug
+report. You may need to use the -s switch to increase the
+internal buffer size so you can capture all the boot messages
+
+
+try booting with devfs=dall passed to the kernel boot
+command line (read the documentation on your bootloader on how to do
+this), and save the result to a file. This may be quite verbose, and
+it may overflow the messages buffer, but try to get as much of it as
+you can
+
+
+if you get an Oops, run ksymoops to decode it so that the
+names of the offending functions are provided. A non-decoded Oops is
+pretty useless
+
+
+send a copy of your devfsd configuration file(s)
+
+send the bug report to me first.
+Don't expect that I will see it if you post it to the linux-kernel
+mailing list. Include all the information listed above, plus
+anything else that you think might be relevant. Put the string
+devfs somewhere in the subject line, so my mail filters mark
+it as urgent
+
+
+
+
+Here is a general guide on how to ask questions in a way that greatly
+improves your chances of getting a reply:
+
+http://www.tuxedo.org/~esr/faqs/smart-questions.html. If you have
+a bug to report, you should also read
