Re: Best stab at questions



After working through these questions (which did help the
presentation[1]), I wanted to highlight these conflicting answers as an
example of what is confusing about the packaging process.  The key to
the answer is the phrase "depends on".  Stephen uses it one context and
Tom another.

Here is how I am addressing it:

        Note: add-on packages that are not dependencies can exist
        outside of EPEL, since they are not needed to build the package
        from source or to support package installation, such as system
        libraries. An example of this is an open source game engine and
        a set of game levels that are not free and open content.  The
        game engine can be built and installed by itself without any
        level, for example, so someone can build free and open levels.
        The levels make for a nicer playing experience, but are not
        required, and could be in an external repository.

Short answers -- all package dependencies must be in EPEL (or RHEL), but
not all things you might "depend on."
