I would like to create a boot CD/DVD for Ubuntu, which boots an encrypted Ubuntu installation.
My intention is security. With a normal encrypted Ubuntu installation, the boot sector & partition are the weak spot. They could theoretically be modified to include a key logger, for example, rendering the encryption useless. A CD/DVD would help here because it's read only.
How do I create a CD/DVD with GRUB (or similar) installed that boots Ubuntu?
