You don't need the full comps file - just the parts you're planning on using. ex: <?xml version="1.0"?> <!DOCTYPE comps PUBLIC "-//Red Hat, Inc.//DTD Comps info//EN" "comps.dtd"> <comps> <group> <id>phy-workstation</id> <uservisible>true</uservisible> <name>Physics Workstation</name> <packagelist> <packagereq type="mandatory">gdm-linuxduke-theme</packagereq> <packagereq type="mandatory">memtest86-grub</packagereq> <packagereq type="mandatory">lyx</packagereq> <packagereq type="mandatory">grace</packagereq> </packagelist> </group> </comps> Then your workstations need only do: yum groupupdate "Physics Workstation" and any new mandatory or default packagereqs added to that group will be added onto the system. -sv
