Bug Description

The documentation for the SSH module should mention that it is working with SSH *Host* Keys, since many people will commonly understand the term "SSH Key" to mean a key being used for User Authentication. This is somewhat ambiguous, I ended up building my own solution to replace host keys.

The wording could be:
Summary: configure ssh and ssh host keys

This module handles most configuration for ssh and ssh host keys. Many images have default ssh host keys, which can be removed using ssh_deletekeys. This prevents re-use of a private key from an image on multiple machines. Since removing default keys is usually the desired behavior this option is enabled by default.

Hi Nils,

Thanks for the bug report! I agree that the wording currently is misleading. It is worth noting that the SSH module does handle _both_ SSH host keys and user authorised keys; any new summary should probably make that clear (I was going to write "clearer" but it isn't at all clear at the moment!).

Would this be a change you would be interested in contributing to the project?

Thanks again!

Dan

Great to hear! Yep, you'll need to sign the CLA. Details on how to do
that (and other guidance on how to contribute) can be found here:
