systemd_default_mount_options: 'defaults'
# The systemd mounts dictionary is a set of mounts that will be created. The
# dictionary can contain the following options:
# `config_overrides` -- (optional) used to inject extra configuration options into the mount file.
# `what` -- (required) Define what will be mounted. This can be a network target.
# `where` -- (required) Where will the "what" be mounted. Required when type is not swap.
# `type` -- (required) The type of file system that will be mounted.
# `options` -- (optional) Any optioned required to make the mount point work.
# If no options are provided the default will be used.
# This list is comma separted. See
# `systemd_default_mount_options` for more details.
# `state` -- (optional) system state of the mount point. The default will omit
# the state so that it is not started or stopped
# unessisarily. If it is desirable for this role to
# start/stop the mount immediately this can be done by
# setting the state to ["started", "stopped", "absent"].
# If the state is absent the mount will be stopped and
# unit file deleted.
# `enabled` -- (optional) Set a Boolean to enable or disable the mount, the
# default is set to "true".
