[opensuse-buildservice] using openSUSE:Tools breaks pkgs

I switched a few packages from tar_scm to obs_scm. This brings the pkgs into state "unresolvable". To fix that I added openSUSE:Tools into the path, the repository looks now like this: <repository name="SLE_12"> <path project="SUSE:SLE-12-SP3:Update" repository="standard"/> <path project="openSUSE:Tools" repository="SLE_12_SP3"/> <arch>x86_64</arch> </repository> Once I did that I noticed that each and every package in the prj was republished. One of the reasons is: an outdated systemd-rpm-macros.rpm is used during build. It should have been 3-10.6.1, but infact 3-8.374 is used. Why does "openSUSE:Tools" override the "SUSE:SLE-12-SP3:Update" path? I thought there is some ordering, the first one wins. Olaf
