Red Hat Enterprise Linux System Roles provides a configuration interface for Red Hat Enterprise Linux subsystems, which makes system configuration easier through the inclusion of Ansible Roles. This interface enables managing system configurations across multiple versions of Red Hat Enterprise Linux, as well as adopting new major releases.
Since Red Hat Enterprise Linux 7.4, the Red Hat Enterprise Linux System Roles packages have been distributed through the Extras channel. For details regarding Red Hat Enterprise Linux System Roles, see https://access.redhat.com/articles/3050101.
Red Hat Enterprise Linux System Roles currently consists of five roles:
  • selinux
  • kdump
  • network
  • timesync
  • postfix
The postfix role has been available as a Technology Preview since Red Hat Enterprise Linux 7.4.
The remaining roles have been fully supported since Red Hat Enterprise Linux 7.6. (BZ#1439896)
