Some thoughts.
I agree with Pete's distinction between configuration and settings. Although
I have heard "configuration" used to identify a set of settings, using
"settings" to identify a physical configuration seems quite inappropriate.
Coming from a hardware background, I regard "component" at a much lower
level than "subunit", although technically the word is correct at any
level... that is, anything may be considered a component of something.
"Subunit" retains a physical connotation while component can apply to
anything. Although it might be a bit muddy as to what a unit is, in this
context a unit would tend to refer to a physical entity performing a primary
function. A sub-unit would be one step down. So the term would imply some
physical component performing a relatively high level function. Component
would have no physical or functional connotation; it is just, in some way, a
part of something.
Clear physical terms are often use for "logical" entities, so things get
pretty foggy. Although the terms must be defined in the document, it would
better to follow general usage in of the intended audience. So I guess that
is the answer and the question.

I, too, hate our use of the term "subunit" and support the change to
"components."
I also strongly agree with Pete that I don't want the proposed change.
Components are constituent elements. Configuration is the relative
disposition or arrangement of elements. Therefore, the Configuration is
made up of Components.
Capabilities depend on the available Components, or the Configuration.
Settings is a collection of Capabilities and their current state. (We'll
ignore Heisenberg's uncertainty principle)

Hi Pete,
I see you what you mean, but...
Be aware that DMTF CIM Core WG hates our term "subunits" and has made
us completely replace it with their term "components".
"Configuration is" just too inherently ambiguous. "Xxx" is just as
meaningful,
if the intent is to imply components.
Cheers,
- Ira
