      I would like GRUB to display a warning when the system is not configured to use secure boot.

          To increase security for those that want it?

            Hm, this seems to overlap in functionality with GRSec a bit.

              Because hacking servers is big business right now, and people are trying to stop that?

                More security is always better, but there's the other side too: Has anyone an idea how this would influence the desktop experience of a normal user? Ideally, there would be no difference, but seeing the depth of some (/dev/port, hibernation) of the changes makes me wonder.

                  No it isn’t. Better for what? Security is a means to an end, not an end in itself.

                  Has anyone an idea how this would influence the desktop experience of a normal user?
                  Has your “experience” been impacted much by the coming of SELinux or AppArmor?

                    But people already stopped that: the GRsec kernel team.
