(Secret Hacker Rule #11: Hackers read manuals. :-) Really, I tried to do my best to find any mistake I made, especially because I'm a new and unexperienced 'player' of -current, and so I read the 'usual suspicious', where I found these hints to turn off debugging code, compile with -DNO_WERROR and so on... To be sure, I append my kernel config, but I would be surprised if there's anything critical - maybe something unnecessary.... Anyway - thanks so far Matthias +++++++++++++++++++++++++ 8>< ++++++++++++++++++++ # # CURRENT -- Specific kernel configuration file for FreeBSD/i386 # # For more information on this file, please read the handbook section on # Kernel Configuration Files: # # http://www.FreeBSD.org/handbook/kernelconfig-config.html # # The handbook is also available locally in /usr/share/doc/handbook # if you've installed the doc distribution, otherwise always see the # FreeBSD World Wide Web server (http://www.FreeBSD.org/) for the # latest information. # # An exhaustive list of options and more detailed explanations of the # device lines is also present in the NOTES configuration file.
