The previous patch moved the configs/base-{generic,debug} to configs/fedora.
Now we update the scripts to reflect that change. Changing the scripts
was straightforward. Handling overrides that didn't use generic names
was a little trickier.
To handle random override names (well rhel), I added some extra logic
in the config_generation script called "ORDER". This tells the scripts
which configs to lay down first and which one overrides it.
Through some testing, I realized I could simplify things and just create
an outer 'order' loop. This removed some duplicated code.
The other change is the 'skip_if_missing' flag. The overrides directory
will not mimic the baseline directory layout 100%. Ensure the baseline
config files are all there, but allow the overrides to have missing files.
Tested on my Fedora and my RHEL tree with success.
