One of the packages I maintain is mercurial. Frequently (e.g., now), there is a rc version available for test. It will probably break some other package that depends on it. I am thinking of a model like google uses for chrome. I could install any of: google-chrome-{stable,beta,unstable} I don't think fedora uses this model anywhere. AFAICT, in Fedora there is always only 1 version available - although there could be one in updates- testing. But the purpose of updates-testing is now for a long-lived parallel development - it is designed for short term before promotion to stable. Although the google-chrome model is perhaps not the ideal way to handle the idea of alternative versions - it seems good enough.
