I don't really want to do that. I think the best course of action is to convert the spec files so that they can work both with and without SCL (there are instructions on the SCL package page, and lots of rpm macros to use), then have ruby 2.0 and ruby24 scl versions of all of our packages. There may even be scripts which can convert spec files to be SCL-ized. I wonder if we can add ruby24 as a "platform" e.g. have a single spec file, and build e.g. fluentd-1.0.el7.x86_64.rpm and fluentd-1.0.el7ruby24.x86_64.rpm ? > > Matthias
