kernel source code

Wed Mar 30 11:00:20 UTC 2005

Can anyone enlighten me as to what this is supposed to mean?

      In order to eliminate the redundancy inherent in providing a separate 
package for the kernel source code when that source code already exists in 
the kernel's .src.rpm file, Fedora Core 3 no longer includes the 
kernel-source package. Users that require access to the kernel sources can 
find them in the kernel .src.rpm file. To create an exploded source tree 
from this file, perform the following steps (note that <version> refers to 
the version specification for your currently-running kernel):
         1.            Obtain the kernel-<version>.src.rpm file from one of 
the following sources:
DONE
         2.            Install kernel-<version>.src.rpm (given the default 
RPM configuration, the files this package contains will be written to 
/usr/src/redhat/)
Presumably rpm -i ....src.rpm - DONE
         3.            Change directory to /usr/src/redhat/SPECS/, and issue 
the following command:
            rpmbuild -bp --target=<arch> kernel.spec
            (Where <arch> is the desired target architecture.)
DONE
            On a default RPM configuration, the kernel tree will be located 
in /usr/src/redhat/BUILD/.
         4.            In resulting tree, the configurations for the 
specific kernels shipped in Fedora Core 3 are in the /configs/ directory. 
For example, the i686 SMP configuration file is named 
/configs/kernel-<version>-i686-smp.config. Issue the following command to 
place the desired configuration file in the proper place for building:

            cp <desired-file> ./.config
Errr- where are you supposed to be when you do this (cadidates are in this 
case /usr/src/redhat/BUILD/kernel-2.6.10/linux-2.6.10/configs or 
/usr/src/redhat/SPECS/)

         5.            Issue the following command:

            make oldconfig
Errr - where are you supposed to be in this case? presumably where there is  
the top level makefile is?

And where are the sources supposed to end up? the directory 
/usr/src/redhat/BUILD/kernel-2.6.10/linux-2.6.10 doesn't seem very 
general... I guess it is appropriate to copy this to /usr/src?

I did have one minor complaint about the behaviour of yum and 
kernel-sourcecode before and that was that yum insisted in deleting 
sourcecodes from other kernel versions making it a pain to upgrade gently.  
Still it was easier than this...

Thanks,

SA
