"""
Mount/unmount a ``kernel`` client.
The config is optional and defaults to mounting on all clients. If
a config is given, it is expected to be a list of clients to do
this operation on. This lets you e.g. set up one client with
``ceph-fuse`` and another with ``kclient``.
Example that mounts all clients::
tasks:
- ceph:
- kclient:
- interactive:
Example that uses both ``kclient` and ``ceph-fuse``::
tasks:
- ceph:
- ceph-fuse: [client.0]
- kclient: [client.1]
- interactive:
