I installed a remote and headless ubuntu box with full disk encryption and dropbear to unlock it by ssh.
I accepted the "standard" host key in my configuration - but now, on every reboot, I have to edit my known_hosts or add -o 'StrictHostKeyChecking no' to the ssh command. But this is bad - a mitm to catch my luks passphrase is a realistic attack vector...
Is there an option to add two host keys for one Host or an explicit "-o AcceptHostKey [fingerprint]" option in ssh?
