I hadn't swapped out all the instances of rawhide in the instructions in
my previous PR. Also remove `enforcing=0` since SELinux should work now.
And graphical boot should work fine now as well, but just inherit
whatever is the default from the current `/proc/cmdline`.
Even though this is the `master` branch, I think it still makes more
sense to point folks to the latest *stable* content here when following
instructions.
Also turn on GPG verification since that should work now.
