# ============ Notification System Options =====================
# Notifications can be sent when images are create, updated or deleted.

# ============ RBD Store Options =============================
# Ceph configuration file path
# If using cephx authentication, this file should
# include a reference to the right keyring
# in a client.<USER> section

# RADOS user to authenticate as (only applicable if using cephx)
