I was reading over the Cobbler Wiki page and found

I am not sure what the page is trying to discuss -- or why this is
a new thing specific to metal as the things mentioned are no
different in Spacewalk if doing reinstalls or guests. If it's the
general topic of "how do I manage diverse kickstart configurations
that may span multiple sites" the answer is "templating", and "it
varies greatly based on site". I can see where the wizard based
kickstart-generator engine in Satellite would have some workflow
problems with this, yes. Cobbler is designed to solve all of
those, so I think the question can be closed?

Anyone care to comment or shall I Wiki Garden this as closed?

oops, this got missed by me. Basically that page was a brainstorming
session Dave and myself had over the workflow of doing PXE based
installs. We were curious about how customers setup and manage large
scale (and small) PXE environments and if what we have built with
spacewalk and cobbler will suit their needs.
Basically a way to further refine future changes to spacewalk-cobbler
to better meet the needs of our users beyond Spacewalk 0.4 and 0.5.
We were contemplating doing some sort of survey of our Spacewalk,
Satellite, Cobbler and other users on how they use (or don't use) our
products to do their kickstarts.
perhaps this wiki page and a survey isn't the right place for that
kind of thing. It might be worth doing this kind of research *after*
Spacewalk 0.5 is out and Satellite 5.3 is available so more people
have our product in front of them vs talking to people about things
they may not have access too.

I think you're right, let them try to the tools and if that indicates
there is a workflow improvement to be made in Spacewalk you'll hear
about it. I was looking over that and even the DHCP lab setup page
and on a whole I found them to be too complicated -- setting up those
things are pretty easy to do, and I tried to make appropriate
edits/comments.
FWIW, there are some quite large (and small) setups using Cobbler, and
I don't see the Spacewalk-using-Cobbler workflow as conflicting with
that.
Not to scare folks, but one recent mailing list post talked about
someone looking to have their setup up to 2 cobbler masters and 18
slave servers. I don't think simple bare metal workflow is a user
concern -- people get it. The interesting challenge I think we have
is finding ways to manage multiple geographies/datacenters (like the
above setup), with DHCP and DNS management turned on, and to do things
like Beaker can do with controlling multiple cobbler servers. Of
course this is a good problem to have.
To go out on a tangent, recent discussion on Cobbler list about
supporting QMF might serve as a very nice way to do that kind of
communication, replacing rubygem-cobbler and Spacewalks cobbler
interface code with something a bit more multi-server aware. I hope
to do some exploration in the next few weeks.
If Spacewalk can just manage the masters, the slaves should be
manageable automatically by the cobbler master.
Anyhow, I really don't see workflow being a problem -- and if you do
want to discuss how people are doing baremetal, let me know. It's
really a simpler thing than just reinstalls, so I can't see any new
workflow problems coming up -- but if they do, I think you'd hear
about them :) The summary is that the workflow problems we really
want to discuss are the ones dealing with multiple geographies, the
workflow of how you deal with a single server spacewalk install is
pretty much solid, I think, but we'll hear what people say.

Related question to the multi-node thing, are there instructions on
setting up Spacewalk in a HA environment somewhere? I'd be interested
to see how that is handled.
(Whether something like linux-HA's heartbeat+stonnith or something else)
