From Fedora Project Wiki
The boot-options documentation is now part of the Anaconda source repository. This allows for us to maintain multiple versions of the documentation, matching up with various releases of Anaconda. Unfortunately, it also means all your old links are dead, the links to specific sections are rendered differently than the wiki. You will have to update this manually.
The latest version of the documentation is always at anaconda on github, and the rendered document can be found in the Anaconda documentation
