Not only should the UAC be made more granular, but so should the package selection at install time. I'm not a fan of Red Hat, but take the RPM: you select a package - if it has any dependencies on other packages it tells you. You can then decide as to whether you want those packages on your system, or if you'd prefer to give it a miss. This way, you see what packages are a neccessity and which ones are optional extras. Works a charm. Many versions of Linux that I prefer (including Suse 10 +) also have this feature.
