sshd[18263]: /etc/ssh/sshd_config line 73: Deprecated option UsePrivilegeSeparation

Sandboxing is now enabled by default in OpenSSH, across all platforms/distros. See the changelog.

Likewise, these two options for the client config are not understood in recent versions of OpenSSH

 HostsRSAAuthentication no                                                                                  
 RSAAuthentication yes

@chris-rock, @atomic111 @mms-segu you guys still interested in maintaining this stuff? I will join and help out.

Hey @ageis, of course we're still maintaining this. :)

There are now several options in recent OpenSSH-versions that are deprecated or removed entirely. I guess we should change the template for these options so depending on the version of OpenSSH they're included or not, e.g. like this.

{% if version < 6.7 -%}
HostsRSAAuthentication no                                                                                  
{% endif %}

What do you think? Do you want to implement this?

Here's another one that is deprecated in the client: UseRoaming.

I do actively use these roles and would love to implement but it will be a couple days before I can send you a PR.
