Hi Thomas,
Thanks for sharing! That may work for me, though for supplying two files an RPM feels heavy-handed. Is this how every SIG includes a custom dist tag in builds?
Where are you placing the buildsys-macros-<disttag> RPM, and how are you including it in Koji?
@Jan, my organization supplies a custom "cantos-release" RPM, so I guess I could just include that as well, since it has the correct macros content.
