 2. Only ED25519 SSH keys are accepted with the SSHD hardening configuration. If you do not use ED25519 keys, you will need to adjust the `/etc/ssh/sshd_config.d/10-custom.conf` file accordingly.
 3. If you create a passwordless user that requires administrative privileges, ensure that it is part of the `sudo` group (CoreOS allows this group to use sudo without a password) as the configs will disable empty password system authentication.
 4. These configurations are made with a VPS in mind. You should adapt it for a bare metal deployment if that is what you are using (adding additional kernel parameters, configuring drive encryption, configuring storage, etc). You should also change the tuned profile from `virtual-guest` appropriately.
