Re: Decrypting LUKS from initramfs; was: Re: ext2 for /boot ???

The obvious problem there is an attacker who gets hold of the
initramfs in order to be able to use the credentials to request the
passphrase themselves. For those who wanted to get more elaborate
(and more likely to mess up and leave their server a useless
encrypted brick), there are things like Mandos:



     "This is the the Mandos system, which allows computers to have
     encrypted root file systems and at the same time be capable of
     remote and/or unattended reboots.

     The computers run a small client program in the initial RAM disk
     environment which will communicate with a server over a network.
     All network communication is encrypted using TLS. The clients
     are identified by the server using an OpenPGP key; each client
     has one unique to it. The server sends the clients an encrypted
     password. The encrypted password is decrypted by the clients
     using the same OpenPGP key, and the password is then used to
     unlock the root file system, whereupon the computers can
     continue booting normally."

How dos this address the above concern ?
