* Bill Oliver:
Is there anything like that for fedora?
There is some work on TPM support for LUKS. I don't know if it has
made its way into Fedora, though.
It would probably be pretty easy to hack the gpg source code to add
a few lines to append system information to the passphrase, but if
there's something already around, I'd like to play with it...
This isn't very secure, you also need to make sure that the
information cannot be copied. TPM achieves that.
