[Bug 1871879] [NEW] Configuring a user should not configure root's authorized_keys

 

Public bug reported:

When `ssh_authorized_keys` is configured in user-data key are
unconditionally copied into /root/.ssh/authorized_keys.

If `disable_root` is set to true it leaks the actual configured
username: "Please login as the user XYZ rather than the user root." With
`disable_root` is set to false you can login.

It would be great if there were a way to actually disable root and not
touch it at all. I fully understand that the info message is useful for
new users, but it would be great to have a way to leave root alone.
