Yes, precisely.

This works as expected, thanks, but it assumes you *know* that %{name}
is in the %_sourcedir macro definition.  Is there a generic way to get
rpm to provide the value of a macro defined from within a spec file?
(this is already done when creating the different rpm scriplets)

You mention that there are easier ways of getting a path. Perhaps you
could elaborate?
