My question is: what would happen when one should use - as

a bootable CD like System Rescue Disc? (I am guessing that

The openSUSE installation DVD will of course boot, having all the
proper signatures that you needed to install the OS in the
And it will be booting the kernel present on the DVD, which is
the SUSE key.
In case you wanted to create your own rescue DVD that'd be booting
custom kernels, that'll be possible, too, using the same shim
you'll be able to enroll your MOK, or just use one if already
Thank you for confirming what I suspected.
My apologies for using the wrong name for the CD I mentioned
above, however I was wondering how a bootable CD such as the
SystemRescueCD which comes from systemrescuecd.org
), and similar
bootable media, would boot under this UEFI process?
It was my impression that most UEFI bios solutions would not test CD
Forcing CD/DVD boot media to be signed with a well known key would end
the use of CD/DVD boot media for all but Microsoft I suspect.
(ie. How does the initial openSUSE install get on to a box if install
media doesn't have a way around the signing/validation rules.)
The same will also need to apply to USB boot media I hope.
Sorry for being 'dense' on this matter but a bootable disc like
SystemRescueCD is a Linux bootable disc which loads a system with a
kernel and contains many tools to be able to access and alter an
existing system installed on an HDD. I even used this disc to remove
encryption from my /home directory when an update to openSUSE 12.1 went
wrong. Would such a disc be affected by this UEFI?
