Add RHEL8 and RHEL9 support

README.md

@@ -6,8 +6,9 @@ An Ansible playbook for automating system bootstrap processes in an Infrastructu
 Most of the roles are adaptable for use with systems beyond ArchLinux, requiring only that the target system can install a necessary package manager, such as `dnf` for RHEL-based systems. Additionally, a replacement for the `arch-chroot` command may be required for these systems.
 
 **NOTE**:
-- RHEL Systems are not currently supported due to restricted access to their repositories.
+- For RHEL 8 and RHEL 9, repository access requires the `rhel_iso` variable. This variable specifies a local ISO or proxy repository.
-  A workaround could involve using an ISO as a local repository or setting up a proxy repository to facilitate access.
+- RHEL systems do not support `btrfs`. Use `ext4` or `xfs` as alternatives.
+- For RHEL 8, `xfs` may cause installation issues; `ext4` is recommended.
