It doesn't explain the individual files at the moment (although there is some copy in the sources for it) because it's information that you don't really need to get the system going, and I didn't want to overwhelm new users. I'll look at adding the info in an appropriate section. Until then, grubx64.efi is the actual grub second stage binary, MokManager.efi is for signature management, shim is the part that is signed and allows SecureBoot to work. -- -- Pete -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Fedora Code of Conduct: http://fedoraproject.org/code-of-conduct Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
