Red Hat Linux 9 Technical Changes
There were many changes between RHL7.3 and 8.0, for example, the use of root=LABEL=/ in the /boot/grub/grub.conf file, the replacement of Xconfigurator with the redhat-config-xfree86 program, and the new dhclient DHCP client daemon that skips trying to bring up interfaces that have no link. There are not nearly as many behavioral changes from RHL8.0 to RHL9, yet the ones that exist are significant." (Thanks to Greg Bailey)
