It sets sequential=false for the items in that set and it definitely
behaves differently when I use it.

Not exactly. That may have been a poor example but what I was trying
to achieve was the idea that these 2 services must run on the same
host, but that neither one had to be runni

True- but then you run into the problem of not being able to have
groups of groups. So if I create a group for my filesystems- I can't
create another group that in

I apologize if this is obvious or has been answered before but my
foogle-fu is failing me.
I'm trying to create a resource dependency tree similar to this one from VCS:
// resource dependency tree

Oracle OraInstance1

Mount OraBi
