Description Christian Glombek 2020-11-24 16:47:43 UTC

Description of problem:

On FCOS, SSH key lookup from the /home/core/.ssh/authorized_keys.d/ directory
is currently disabled, which might yield unexpected results or even potential security issues when only /home/core/.ssh/authorized_keys is rotated.

Lookup from /home/core/.ssh/authorized_keys.d/ should be disabled altogether.

On RHCOS this is no an issue, as it already looks up SSH keys from the
authorized_keys file only.
