If someone don’t like using CLI by finger, I’ve wrote unofficial GUI for FedUP (KFUpgrade) – it can download files for upgrade to F19/20/21 (Alpha). Next Step after GUI is Step 2.6 from Your tutorial – start upgrade in GRUB. I’ve wrote it for myself, but under GPLv3 license and source code is distributed with application, so it’s available for everyone :-)

To work it only need Java JRE installed (Oracle or OpenJDK) and Xterm (rpm is not avaible at this moment, lack of knowledge how to build it, so depends must be installed manually).
