http://vyos.net/wiki/Upgrade makes it clear not to use dist-upgrade, but should apt-get upgrade be ran? I tried it in a VMware Workstation image (snapshotted before upgrading) and my config was lost, and end of boot messages were spitting out something about Amazon EC2 SSH keys or something :frowning:
