If you use system roles to carry out these processes, you can also ensure the stability of subsequent deployments. Thanks to the characteristics of automated processing, future RHEL upgrades can be smoother and reduce various interruptions in the upgrade process.

In addition, RHEL9.2 and 8.8 also add three system roles: rhc (Remote host configuration), journald (Systemd-journald) and ad_integration (Microsoft Active Directory integration).

The ad_integration is added to the rhel-system-roles suite, the full name is rhel-system-roles.ad_integration, which can assist the RHEL system to integrate directly into Active Directory, making it easy for administrators to centrally control all the behavior of the user group.

Rhc, which is added to the rhel-system-roles suite, is a support service that automatically registers users' RHEL systems with Red Hat Subscription Management (RHSM) or Satellite servers, making it easy for users to contact Red Hat experts immediately to solve all kinds of problems that may be encountered in the process.

As for the journald system role, you can automatically set the systemd log collection configuration for the RHEL system. It is basically a log memory, which is more convenient for users to continuously collect the log information of the system.
