Bootstrap options
-----------------
Because some configuration options affect the process's ability to
contact the monitors, authenticate, and retrieve the cluster-stored
configuration, they may need to be stored locally on the node and set
in a local configuration file. These options include:

In the vast majority of cases the default values of these are
appropriate, with the exception of the :confval:`mon_host` option that
identifies the addresses of the cluster's monitors. When DNS is used
to identify monitors a local ceph configuration file can be avoided
entirely.
In most cases, the default values of these options are suitable. There is one
exception to this: the :confval:`mon_host` option that identifies the addresses

configuration file can be avoided entirely.
Skipping monitor config
-----------------------
Any process may be passed the option ``--no-mon-config`` to skip the
step that retrieves configuration from the cluster monitors. This is
useful in cases where configuration is managed entirely via
configuration files or where the monitor cluster is currently down but
some maintenance activity needs to be done.
