This is important for the binary repository scripts, so it's feasible to test the binary package build and challenge process locally without setting up a new chroot whenever changing the repo URLs. Also it behaves a bit more intuitively, because it really uses the repo URL specified on the commandline, even when the chroot is already set up.
