Yes.. Your advice was to use 'fedpkg local' which does indeed work but
it also builds a bunch of rpms I don't need or use, like debug kernels.

When I rpmbuild from a srpm I use the following flags
   --without extra --without tools --without debug --without perf --without headers

which greatly decrease the compiling time... from 70mins to 30mins
depending on the machine... 

Now if I can set those flags in the fedpkg local build... Then
I'm good to go...

All I'm trying to do is build from a source rpm so I can set those flags.
Here is what I'm doing... If there is a better way please let me know... 

fedpkg clone kernel
cd kernel
fedpkg srpm
rpm -ihv kernel*.rpm
cd /home/src/SPEC
rpmbuild -bb --without extra --without tools --without debug --without perf --without headers --target x86_64 kernel.spec

I've been build kernels this way for quite a while... but again,
if there is a better way I'm more than willing to try...

Thanks for the cycles!
