Although the project is still open to other possibilities, Garrett said, purchasing a key from Microsoft has thus far been the most feasible way of running Fedora on UEFI machines.
Nonetheless, the act of relying on Microsoft to give its approval to run Linux on a computer may be a bitter pill for many longtime open-source advocates, who remember Microsoft's once-hostile stance toward open source. "What is Fedora's plan if Microsoft changes these terms of their $99 signing program to exclude you?" one commenter to Garrett's post asked.
Last year, Microsoft announced that all computers running its Windows 8 operating system will need to require firmware to support UEFI. On x86 systems, it can be turned off, though computers running ARM processors will not have this option. Garrett was less worried about the mandatory UEFI on ARM computers because Microsoft's influence over these vendors is not as expansive.
