Database migrations are the tricky part of any deployment. They make zero-time deploys problematic. They requires special attention since they can break stuff.

PDF should be this nice universal format that many government institution now work with. But what if they require you to fill in XFA forms inside their template PDFs? The ones I need to fill for my insurance company are certainly not supported in the standard Document Viewer shipped with Fedora. This weekend I tried installing Master PDF Editor and guess what? It works like a charm for me. They even offer various RPM builds for CentOS 6/7. And they work on my Fedora out of the box. Lucky me. Thanks a lot for this!
