Server Fault is a question and answer site for professional system and network administrators. It's 100% free, no registration required.

I've a system that has numerous RPMs with the label .fc6 - but it is an RHEL 5.4 system. It is not impossible that it was updated from CentOS 5, but can't be certain. Others are labeled with .el5 and some with "jpp" - but most have no such suffixes.

It also has numerous dual architecture items loaded, with i386 combined with x86_64.

Does RHEL contain Fedora Core packages? Does CentOS contain Fedora Core packages? Whatever for? What is JPP?

Update: Looks like jpp packages might be from JPackage.

RHEL 5 (and thus CentOS 5) was derived from Fedora Core 6. Not all packages needed to be modified for use in RHEL and so they retained the ".fc6" designation in the package release value.

Are JPackage packages also included? From my readings, Red Hat was involved in JPackage (albeit the project seems to be languishing). –  Mei Mar 9 '11 at 19:25
    
Those most likely were pulled into Fedora Core and from there found their way into RHEL. –  Ignacio Vazquez-Abrams Mar 9 '11 at 19:27
