client::
space delimited list of client ip/networks for use in /etc/exports. See exports(5)
OPTIONAL PARAMETERS
-------------------
options::
export options for use in /etc/exports. See exports(5)
export::
the directory to export. Defaults to object_id
state::
Either present or absent. Defaults to present.
EXAMPLES
--------
--------------------------------------------------------------------------------
__nfs_export /local/chroot/lucid-amd64 \
--client "192.168.0.1/24 10.0.0.1/16" \
--options "ro,async,no_all_squash,no_root_squash,subtree_check"
