My group uses nested groups extensively for profiles on workstations vs.
servers, etc.  For example, we have various classes of workstations and
we have groups that add functionality depending on the class.  For
example, a base workstation has certain packages; an engineering
workstation includes the base workstation and adds other packages.  We
prefer to do one "yum groupinstall" for engineering workstation and have
it pull any nested groups as needed.

If yum-2.6 will not have this functionality, for RHEL 5, we would have
to move the source of truth for what gets installed on each workstation
class from inside the yum repo to some class-specific configuration in
our kickstart (i.e. we would have to know that on engineering
workstations, we need to yum groupinstall base-workstation and
engineering).  The movement of the source of truth is a fairly large
problem and we prefer for it to be centralized inside the yum repo /
yumgroups.xml.

Thanks for your help in this.
