Better SSH security

[sgrayban]

If the clock is facing the internet there should be a way to to upload your own ssh key and set root access to PermitRootLogin prohibit-password in /etc/ssh/sshd_config

Note that the admin CLI does not run as root, but an unprivileged user 'admin' with specific sudo permissions for specific commands behind the scenes. But do agree there should be an option to set authorized keypairs instead of or in addition to password auth.

Is it possible to mount the partition(s) - I haven't looked at the insides yet but in one photo you had shows a sdcard or was the pre-production photo?

Regardless of whether or not the device is public facing, I would like to be able to load a public key (and optionally disable password authentication) on the device so that I can ssh in (e.g., using putty with the pageant agent) and not have to log in with a user name and password.
