hi, its installed:

kernel-devel-2.6.18-8.1.3.el5.i686 "Development package for developing 
kernel modules to match the kernel".
kernel-headers-2.6.18-8.1.3.el5.i386 "Header files for the Linux kernel for 
use by glibc"

But, you know its the kernel itself that I am building, not a module, thus 
these are irrelevant.

I don't understand why the RPM build process would build everything 
perfectly, except for
the source output directory being named linux-2.6.18.i686 instead of the 
expected 2.6.18-8.1.3_test.el5-i686.

I decided to see if patches were applied beyond the 2.6.18 level and so 
unzipped "patch-2.6.18.4.bz" that was in SOURCES.

Then I picked at random a section patching Documentation/sysctl/vm.txt 
beginning on line 26 thus:

1    = Zone reclaim on
2    = Zone reclaim writes ...
4    = Zone reclaim swaps ...
-8  = Also do a global ...

I see in my BUILD/kernel-2.6.18/linux-2.6.18.i686 that the patch was applied 
(the last line was taken out), thus the directory name does not reflect the 
actual patch level of the source code.

It seems to be a bug :-\
