I have finally fully completed a Koji 1.6.0 Setup with 7 arm builders.
 
I imported and tagged all the packages as per intructions and linked it to my own personal repo as an external repo for performing builds. A scratch build will work and i can import and link the built rpms to the srpm package.
 
If i try to build a SRPM that has been imported without using the --scratch you get "GenericError: Build already exists".
 
Am i really missing out on the way to operate the system or do you have to scratch build everything and than import them after the rebuilds?
 
I would have guessed that you import all the SRPMs and than build them all in place or mark them for build and sit back and wait. Am i missing a option here or ?
