[ 0x01 - Default root user ]

The root user has a hardcoded password that is unknown and not changeable.
Normally access is only through the restricted shells.

The /etc/shadow file shows the following hash:
root:$1$FGOgdWM7$dac9P0EJgTSX8a4zc4TXJ/:15783:0:99999:7:::


[ 0x02 - Known SSH Private Key ]


The /root/.ssh/authorized_keys on the appliance contains the following key
(same with every deployment):

-----BEGIN DSA PRIVATE KEY-----
