Installing RHEL 9 OS
The installation of the RHEL 9.6 OS should follow the installation guidance provided by the installer. However, the following details shall be considered:
For FOXMAN‑UN R18 installation our requirement for the OS is RHEL 9.6 full ISO
either with the “Server with GUI” option,
or with the “Server only” option,
depending on your requirements.
* 
Please note: 
If you need ALS to be installed with FOXMAN‑UN, or if you will install FOXMAN‑UN with the components “Core + UI” or “UI only”, the “Server with GUI” RHEL 9.6 OS installation option is mandatory.
Configure the partitioning of the local disk if required (mandatory if hardening is required); recommended minimum space is defined in the FOXMAN‑UN R18 Release Note [1KHW002499], section “Server Hardware Platform and Span of Control”. Required minimum partitioning for hardening is defined in the application note “FOXMAN‑UN R18 RHEL9 Hardened Installation” [1KHW029185].
After the standard Operating System (RHEL 9.6) installation, we recommend to connect to the Internet, register the installation with a valid subscription and execute
# subscription-manager release --set=9.6
# dnf update
Because the Zip utility is not available in RHEL 9.6 by default, install it with this command:
$ sudo dnf install zip
