I can't see RedHat commiting themselves to the first 3 in your sense unless they fully support it, which seems unlikely. As to 4, your best guide is probably to compare released versions, and see how the comparisons pan out. From a quick inspection I believe mostly that FC1 >= RHEL3 , but there are packages where RHEL3>FC1. Note also that security/bugfix packages will further complicate things. Michael Young
