 Configuration
===============

Each Ceph process, daemon, or utility draws its configuration from several
sources on startup. Such sources can include (1) a local configuration, (2) the
monitors, (3) the command line, and (4) environment variables.

Configuration options can be set globally so that they apply (1) to all
daemons, (2) to all daemons or services of a particular type, or (3) to only a
specific daemon, process, or client.
