This needs some changes. You don't want to chdir into CORE, since the tests are located in masterfiles. You have to reuse the ``testall`` script to run the masterfiles tests instead. Also, I'd really keep the name ``default.cf.sub``, since that's what people are used to including in their tests. Maybe something like this:

<pre>
check:
  cp $(CORE)/tests/acceptance/default.cf.sub tests/acceptance
  cp $(CORE)/tests/acceptance/testall tests/acceptance
  cd tests/acceptance && ./testall
</pre>
