I have tried to build an exact reproduction of the kernal distributed by SuSE following instructions in the Administration Guide. This produces a Kernal image that is much smaller than the original. Has anyone tried to build an exact reproduction of 8.1, 8.2 or 9.0 that results in the same file byte for byte. Is this even possible? -- ------------ Wolter Works - Always Innovating ------------- - Industry and Commerce Internet Invention - Internet Marketing Product Concepts & Implementation mailto:johnswolter@wolterworks.com John Wolter, President 1531 Jones Drive Ann Arbor, MI 48105-1871 USA 1-734-665-1263 Copyright 2003 John S.

I guess that if you have the same system, same configuration, same compiler, same kernel sources, and all the important stuff is the same, yes Sergio A las 10:18 del 17 de Oct de 2003, John S. Wolter dijo:

-- Stockmayer's Theorem: If it looks easy, it's tough. If it looks tough, it's damn well impossible.
What you say is certainly true, but remember SuSE is producing a distribution. That should have a fair amount, but not complete, of independence of those factors. The difference I am seeing is 1085124 bytes for the distribution verses 924121 for the locally compiled bzImage. Seems like a large difference that can not be accounted for with variations of hardware and software. May be this should be a contest for the flag of honor for getting it right?

You didn't mention what you are using for source... If using the vanilla files from www.kernel.org, you are not using the same source. SuSE adds a lot of patches/additions to their kernels.

Bruce: I'm using the 8.1 distribution and sources for the standard i386 architecture. I have run online SuSE updates. According to my /var/log/boot.msg file this is my SuSE distribution kernel is: Linux version 2.4.19-4GB (root@Pentium.suse.de) (gcc version 3.2) #1 Fri Sep 13 13:14:56 UTC 2002 I do not know if sources are installed if that implies those are also updated.

¿Which commands are you using to compile that kernel? Perhaps these: |After customizing the kernel configuration, start compilation by |entering: | | | earth :/usr/src/linux# make dep | earth :/usr/src/linux# make clean | earth :/usr/src/linux# make bzImage | There is one missing, before those: make cloneconfig which is crucial to reproduce the SuSE kernel. Then, I would highly recomend editing the Makefile and writing something to 'extraversion', like your initials: unless you do that, the original SuSE modules will be replaced by yours Neither of these two things are mentioned on the admin guide, and I don't know why. -- Cheers, Carlos Robinson
