The operating system shell, or the deployment framework of choice, is
best suited to that I think.

Well, unittest is for unit testing (testing of small isolated units of
the code). There are many definitions of “functional testing”, and I
don't think ‘unittest’ is a good choice for any of them.

Reserve the term “testing” for testing the code of your application, I'd
recommend. Libraries designed for “testing” are not good outside that
domain.

If a shell program isn't up to the job, look at deployment tools like
Fabric <URL:http://pypi.python.org/pypi/Fabric/> or Salt
<URL:http://pypi.python.org/pypi/salt/>.
