This bug comes from #1628. Currently, a lot of the components have code like this:

# If B10_FROM_SOURCE is set in the environment, we use data files
# from a directory relative to that, otherwise we use the ones
# installed on the system
if "B10_FROM_SOURCE" in os.environ:
    SPECFILE_LOCATION = os.environ["B10_FROM_SOURCE"] + os.sep + \
        "src" + os.sep + "bin" + os.sep + "ddns" + os.sep + "ddns.spec"
    PREFIX = "@prefix@"
    DATAROOTDIR = "@datarootdir@"
    SPECFILE_LOCATION = "@datadir@" + os.sep + "@PACKAGE@" + os.sep + "ddns.spec"
        .replace("${prefix}", PREFIX)

SOCKET_FILE = bind10_config.DATA_PATH + '/ddns_socket'
if "B10_FROM_BUILD" in os.environ:
    if "B10_FROM_SOURCE_LOCALSTATEDIR" in os.environ:
        SOCKET_FILE = os.environ["B10_FROM_SOURCE_LOCALSTATEDIR"] + \
        SOCKET_FILE = os.environ["B10_FROM_BUILD"] + "/ddns_socket"

It is duplicated code, which is inconsistent in the various copies. Any change in our process (where we install things, or the env variable we use to override settings) would mean editing many files. We should ideally have utility functions such as one that returns a path to the spec file when passed the name of the component.

BTW, I once added the src/lib/python/[.in] file, with the intent to start using that for configure-time variables (instead of generating other python files). We never really gotten around to start using that for most of the currently generated files, and I'm not suggesting we do so in this ticket, but perhaps this would be a good place for such shared path derivation code.
