Secure Boot versus Ksplice.
I have been attending many talks on Secure Boot.  The basic idea behind secure boot is to ensure that the bios/bootloader and kernel have not been hacked.  My understanding of how this is done is everything is signed and verified during the bootup.  Nothing can run in the kernel that was not signed and verified.  

Then we Oracle pushing Ksplice.

I can't help but ask the question?

Is ksplice a security disaster waiting to happen?

Re: An easy answer: no

I am not a kernel engineer.

Nor am I. But I like the idea of ksplice precisely because it might allow me to bypass Secure Boot. I want to be the one making my own security decisions about what I run on my machines. Sure, most users aren't capable of doing that, and Secure Boot might buy them some extra security (or more likely, the illusion of it). But I'm not most users.
