This is part of the Mandos system for allowing computers to have
6
encrypted root file systems and at the same time be capable of
7
remote and/or unattended reboots. The computers run a small client
8
program in the initial <acronym>RAM</acronym> disk environment which
9
will communicate with a server over a network. The clients are
10
identified by the server using an OpenPGP key; each client has one
11
unique to it. The server sends the clients an encrypted password.
12
The encrypted password is decrypted by the clients using the same
13
OpenPGP key, and the password is then used to unlock the root file
14
system, whereupon the computers can continue booting normally.
