We know that Fedora will require a certificate from Verisign, to allow fedora versions to boot with signing keys.
What about anaconda? Will there be a signing key for it. Will I be forced to boot from a DVD because booting from USB is not necessarily available or supported?
What about wanting to boot from a virtual machine? Will the VM have a virtual UEFI software?
Since the Flame virus which made the news the past few days could get around signing certificates, why submit normal users to this extra UEFI hassle?
Will the BIOS software be upgradable, when bios bugs are found? If I was a hacker, that is my "port of entry" to defeat all signatures.
