Settings here will be merged with the rest of the configuration (with the secret settings taking precedence in case of conflicts, and files that occur later in this list taking precedence over those that occur earlier). Recommended settings:

- misc.email_account, misc.email_pwd if email alerts are enabled
- servers.<name>.username, servers.<name>.password.
