It seems that linuxconf has been removed from a "standard" installation, requiring the customer to manually select it from the package list, or install it later from the CD. Many of our customers depend on having linuxconf available, and the extra step to install it creates confusion. Please re-add linuxconf to the "standard" installations.
This is intentional. Linuxconf is now in the list of deprecated packages in the RELEASE-NOTES file on the CD. Red Hat has invested a fair amount of engineering time and effort to provide newer config-tools; sorry, John, but Linuxconf is no longer on the list of mandatory base packages.
I'm glad to see this -- linuxconf always seems to break things on people's systems and then I have to go clean up after it. And it has always seemed to be an unknown security factor, since it doesn't respect hosts.allow/deny (it has its own access control mechanism, which may or may not work or be configure correctly....)
