> By default, when fileinstall creates CM configurations, they have no locations set. According to spec:
> {quote}
> 104.4.2 Dynamic Binding:
> A null location parameter can be used to create Configuration objects that are not yet bound.
> In this case, the Configuration becomes bound to a specific location the first time that it is
> compared to a Bundle’s location.
> It is recommended that management agents explicitly set the location to a ? (a multi-location)
> to allow multiple bundles to share PIDs and not use the dynamic binding facility.
> {quote}
> I'd prefer "principle of least surprise", so CM configs created from {{etc/*.cfg}} files have multi-location is set by default (alternatively - we could have configuration option), so if for example there are two blueprint bundles using {{<cm:property-placeholder>}} for same PID, they can use the configuration without problems
