You need to follow https://fedoraproject.org/wiki/How_to_remove_a_package_at_end_of_life and run those commands. The package is still valid in git.

Also, the package is just gpxe. The list you have are subpackages, and those will be taken care of by blocking gpxe. I've done that for F18 and rawhide now. Please don't forget to do the git cleanup.

Done now (had the changes locally but forgot to push). Thanks Josh!
