One of the things that bugs me about PKI trust chains like this, what happens if the unthinkable happens, and Microsoft's RootCA gets compromised and has to be revoked... does that mean every single piece of UEFI hardware out there needs a BIOS upgrade? and don't UEFI bios updates have to be signed too? -- -john r pierce recycling used bits in santa cruz _______________________________________________ CentOS mailing list CentOS@centos.org https://lists.centos.org/mailman/listinfo/centos
