[Merge] ~toabctl/livecd-rootfs:master-cpc-dont-modify-sshd_config into livecd-rootfs:ubuntu/master

[Robie Basak]

This isn't a full review, but I just wanted to confirm that the approach taken to fix this seems appropriate and reasonable. Thanks!

You might want to verify that sshd_config.d/ support has existed in all the releases you need support for. I think it's a relatively new feature?
