### BEGIN INIT INFO
# Provides:          mongodb
# Required-Start:    $network $local_fs $remote_fs
# Required-Stop:     $network $local_fs $remote_fs
# Should-Start:      $named
# Should-Stop:
# Default-Start:     2 3 4 5
# Default-Stop:      0 1 6
# Short-Description: An object/document-oriented database
# Description:       MongoDB is a high-performance, open source, schema-free
#                    document-oriented data store that's easy to deploy, manage
#                    and use. It's network accessible, written in C++ and offers
#                    the following features:
#                    .
#                       * Collection oriented storage - easy storage of object-
#                         style data
#                       * Full index support, including on inner objects
#                       * Query profiling
#                       * Replication and fail-over support
#                       * Efficient storage of binary data including large
#                         objects (e.g. videos)
#                       * Auto-sharding for cloud-level scalability (Q209)
#                    .
#                    This package is build with V8 JavaScript engine.
#                    .
#                    High performance, scalability, and reasonable depth of
#                    functionality are the goals for the project.
