The software described in this documentation is either no longer supported or is in extended support.
Oracle recommends that you upgrade to a current supported release.
          During installation, Spacewalk generates a CA certificate.
          This certificate is used in the client registration process.
          If a Spacewalk server does not have a valid fully-qualified
          domain name (FQDN), Spacewalk does not generate a valid CA
          certificate. Spacewalk does not consider
          .local and .localdomain
          to be valid domain names.
