Choice #2 is *very* tricky; #1 is by far the better option. It's still not great, but better. I don't have any examples to show you, but the basic idea is to install your versions into a secondary tree and create backups/symlinks in the %post section which get removed in the %preun section. Make sure you check $1 so that these actions only happen for install/erase, NOT upgrades! Upgrades need only replace the existing config files in your package. For example, you have a package called "ukansascfg" which installs your configs into /etc/ukansascfg/gdm/Foo and so forth. Your %post section would loop through those files, moving the original /etc/gdm/Foo to /etc/gdm/Foo.pre_ukansascfg_20061210 and creating /etc/gdm/Foo as a symlink to /etc/ukansascfg/gdm/Foo. You must understand that rpm cannot and will not track this "hostile takeover" of config files, and rpm -V will report numerous problems for each one. You will probably also have to write %triggers for each package whose config files are being replaced so that upgrades to those packages don't overwrite your changes. You can always have your yum repository provide versions of those packages that are "newer" and have your custom config changes already in them. You'll have to track the upstream Fedora package carefully, but tools like Mezzanine (http://beta.kainx.org/wiki/view/Mezzanine) make that job a whole lot easier than doing what I described above.
