Replace ``logger.debug`` with a local ``call``

Instead of having ``noop`` be defined by commenting out invokes of
``subprocess.call``, a local function should be defined that can forward the
request if ``noop`` if False. Notice, for the time being, ``noop`` is
defaulting to True (or don't do anything). This script is still in its infancy;
I'm not ready for it (nor is the test environment) to start _actually_
calling/creating sub shells
Refactor ``call``=> use Popen instead

Allow for stdin piping

Add call for setting root password
Fix logging setup
Add ``main`` and install options
General fix (syntax, typos, etc)
Add nfs configuration
