Debian CD has a security checking option. That might pull in the keyring.

There is a package that will simulate booting from CD. iirc its SBM
(Smart Boot Manager).
A floppy image of that should be on the CD, and a set of usb floppies
for external cdrom drives.

The reason seems to be that all udebs are on the CD, right?
Why do wee need the kernel udeb? Isn't the kernel-iamge.deb installed?

Also a config option in debian-cd iirc.

That doesn't (yet) have the 2. stage udebs or debian-cd magic files on
it. It just makes a bootable cd image of the kernel and ramdisk. Good
for TYPE=netboot when you can't netboot.
