Hey,

I am currently maintaining llvm trunk and mesa git snapshot repos for f25 and f26 at: https://copr.fedorainfracloud.org/coprs/che. 

One thing i would love to see is the ability to have a buildrepo and a release repo and beeing able to sync from build to release once a complete buildchain successfully built.

More thorough description of the problem and a possible solution:

* you have a dependency chain of 3 packages to build
* you need to regen repos after each package because the next package in the tree depends on the first one. (like clang on llvm)
* then after building the first 2 packages the 3rd package breaks ... you end up with a broken dep chain in the repo.

Now a workaround would be to do scratch builds first and then final repo builds. But e.g. for llvm (only the llvm library) that means... over 100 minutes buildtime using 4 builders (32bit / 64bit for 2 distro versions).

What i would love to see is to be able to build in one repository and then send (copy/rsync whatever) the built chain over to a release repository. This way also testing is possible before pushing the stuff to consumers.

kind regards,
Rudolf Kastl

OK.  Thank you for working on it!  I am looking forward to use it one day...
