Its +configuration specifications describe a literal configuration goal +state for clients. In this architecture, the Bcfg2 client tool is +responsible for determining what, if any, configuration operations must +occur and then performing those operations. The client also uploads +statistics and client configuration state information. The design +and implementation of the reporting system is described on a separate +:ref:`page `. + +A comprehensive description of the Bcfg2 Architecture (and the choices +behind the design) can be found at :ref:`architecture-index`. + +Server +------ + +The role of the Bcfg2 server is rendering a client-specific target +configuration description from a global specification. The specification +consists of a directory structure containing data for a variety of server +plugins. The Bcfg2 server has a plugin interface that can be used to +interpret the configuration specification. + +Client +------ + +The Bcfg2 client is responsible for determining what operations are +necessary in order to reach the desired configuration state.

Using +this feature, Bcfg2 provides an objective measure of how good a job an +administrator has done in specifying the configuration of client +systems. Bcfg2 is therefore built to help administrators construct an +accurate, comprehensive specification. + +Bcfg2 has been designed from the ground up to support gentle +reconciliation between the specification and current client states. It +is designed to gracefully cope with manual system modifications. + +Finally, due to the rapid pace of updates on modern networks, client +systems are constantly changing; if required in your environment, +Bcfg2 can enable the construction of complex change management and +deployment strategies. + + +.. toctree:: + :maxdepth: 2 + + architecture-overview + os-support diff --git a/doc/introduction/os-support.txt b/doc/introduction/os-support.txt new file mode 100644 index 000000000..efbc307cb --- /dev/null +++ b/doc/introduction/os-support.txt @@ -0,0 +1,46 @@ +.. -*- mode: rst -*- + +.. _os-support: + +What Operating Systems Does Bcfg2 Support? +------------------------------------------ + +Bcfg2 is fairly portable.
