Greetings. I'm testing the Amazon Free Tier since a few days, and I've
discovered a very simple bug in the above image (ami-5e615343).

The file /etc/ssh/sshd_config says:

HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key
HostKey /etc/ssh/ssh_host_ecdsa_key
HostKey /etc/ssh/ssh_host_ed25519_key

but the last one (ed25519) does not actually exist.

As a result, messages like this one may be found in /var/log/auth.log:

[...] sshd[4859]: error: Could not load host key: /etc/ssh/ssh_host_ed25519_key

The simple workaround is "dpkg-reconfigure openssh-server" but we
might better fix this in the images (cloud-init maybe, I'm completely
new to this).

Thanks.
