If you want to set it up and forget about it, just use any RHEL clone (AlmaLinux is by far the fastest with updates: it took them like a week to ship RHEL 9 after the official release). You set up the system, install & enable `dnf-automatic`, and forget that it exists for the next 10 years.

If AlmaLinux (or any other clone) dies for some reason, you can always move to another clone without re-installation (using their tool `elevate`).
