Allow override of SSH key glob
I have a lot of SSH keys in my ~/.ssh
folder. Thirty or forty or so. I don't want my newly-built images to be able to be logged in to using any of those keys -- just some subset.
So I've added a config file entry, ssh_key_glob
, that defaults to but allows overriding of ~/.ssh/id_*.pub
as the glob for finding public-keys to embed in the image.
