That takes care of updating everything. As you know, Red Hat is no longer offering a free Linux distribution and their current distribution has a $150 subscription fee. It doesn't make sense to have to pay $150 to run your own software, so we've migrated to Fedora as a target platform.
Fedora is the continuation of the free Red Hat distribution, theoretically. Fedora 1.0 is a giant leap forward from Red Hat 9 in terms of C library and compiler behavior. Distributions are changing so fast now in basic functionality that it's anyone's guess whether even the simplest C functions are going to work over a 3 month period so these releases are really a best guess. There is no warranty.
