ITER has been building RPMs for all their software including EPICS modules on RHEL for many years, but I don’t believe they are allowed to share the results with the community for intellectual property reasons (administrative and legal, not for any technical reasons).

Despite running RHEL the APS will never use RPMs because we need the ability to install multiple versions of our support modules simultaneously, without knowing very far in advance which combinations of modules we might need. The EPICS build system was designed with that model in mind, and the Sumo tool from HZB (BESSY) makes it very easy to manage and build EPICS support modules using that model. For the APS Upgrade project we are using a combination of Conda packages for user applications and Sumo for EPICS IOC code.
