Hi all,
I have just posted the following wiki page to reflect a refined proposal
for HOT software configuration based on discussions at the design summit
last week. Angus also put a sample up in an etherpad last week, but we did
not have enough time to go thru it in the design session. My write-up is
based on Angus' sample, actually a refinement, and on discussions we had in
breaks, plus it is trying to reflect all the good input from ML discussions
and Steve Baker's initial proposal.

Please review and provide feedback.
I believe there's an error in the Explicit dependency section, where it
says that depends_on is a property. In cfn DependsOn actually exists at
the same level as Type, Properties, &c.
resources:
client:
type: My::Software::SomeClient
properties:
server: { get_resource: my_server }
params:
# params ...
depends_on:
- get_resource: server_process1
- get_resource: server_process2
And conceptually this seems correct, because it applies to any kind of
resource, whereas properties are defined per-resource-type.
Don't be fooled by our implementation:

It also doesn't support a list, but I think we can and should fix that
in HOT.
cheers,
Zane.
