Description:
 def get(hostname, username=None, fallback=None, detect_sudo=True, use_rhceph=False, callbacks=None):
 """ Retrieve the module that matches the distribution of a ``hostname``. This function will connect to that host and retrieve the distribution information, then return the appropriate module and slap a few attributes to that module defining the information it found from the hostname. For example, if host ``node1.example.com`` is an Ubuntu server, the ``debian`` module would be returned and the following would be set:: module.name = 'ubuntu' module.release = '12.04' module.codename = 'precise' :param hostname: A hostname that is reachable/resolvable over the network :param fallback: Optional fallback to use if no supported distro is found :param use_rhceph: Whether or not to install RH Ceph on a RHEL machine or the community distro. Changes what host module is returned for RHEL. :params callbacks: A list of callables that accept one argument (the actual module that contains the connection) that will be called, in order at the end of the instantiation of the module.
