Hi everyone,

Please be aware that there are a number of issues with using coldkernel
in the Fedora templates currently. Our goal is to push out 0.9b over the
holidays to address this.

For the time being, the Fedora instructions have been entirely removed
from the master git branch, and progress will be made on the 0.9b
branch, along with Whonix support.

Happy Holidays!
