Afaik it would allow to securely enter hard disk encryption passwords
via network on a Fedora system, because one can ensure that the correct
(untampered) initrd / kernel is loaded.
You cannot simulate this afaik because the used cryptographic keys are
only stored in the TPM module and cannot be accessed from the outside.
Therefore one needs to tamper with the TPM module instead of only with
the unencrypted /boot partition, which is a lot harder from my point of
So you can't possibly duplicate the keys elsewhere and modify the software
calling them to look in that place, allowing you to virtualize a whole
cluster of the same "trusted" machine?
