So, instead of issuing a command like -

Example Only -

patch -p1 < /usr/src/device-mapper.1.01.05/patches/linux-2.4.28-pre4-devmapper-ioctl.patch

You would add it to the spec file to be automatically included when you did
the  'rpmbuild -bp --target=i686 kernel-2.6.spec'

I might figure all this stuff our after all.....

Then I'd put my patch file in /usr/src/redhat/SOURCES/ and
