Note: this daemon reloads it's config when the SIGHUP signal is received. .SH OPTIONS .IP "--help, -h" Print the help message .IP "--log-level, -g value" Specify how detailed logs should be. Possible values: 'error', 'warning', 'notice', 'info', 'verbose', 'debug' .IP "--debug, -d" Enable debugging output .IP "--verbose, -v" Output verbose information about the behaviour of the agent .IP "--version, -V" Output the version of the software .IP "--file, -f value" Specify an alternative input file than the default. This option is overridden by FILE if supplied as argument. .IP "--define, -D value" Define a list of comma separated classes to be defined at the start of execution .IP "--negate, -N value" Define a list of comma separated classes to be undefined at the start of execution .IP "--no-lock, -K" Ignore locking constraints during execution (ifelapsed/expireafter) if "too soon" to run .IP "--inform, -I" Print basic information about changes made to the system, i.e. promises repaired .IP "--diagnostic, -x" Activate internal diagnostics (developers only) .IP "--no-fork, -F" Run as a foreground processes (do not fork) .IP "--ld-library-path, -L value" Set the internal value of LD_LIBRARY_PATH for child processes .IP "--generate-avahi-conf, -A" Generates avahi configuration file to enable policy server to be discovered in the network .IP "--color, -C value" Enable colorized output. Possible values: 'always', 'auto', 'never'. If option is used, the default value is 'auto' .IP "--timestamp, -l" Log timestamps on each line of log output .IP "--graceful-detach, -t value" Terminate gracefully on SIGHUP by detaching from systemd and waiting n seconds before terminating .IP "--ignore-preferred-augments, -" Ignore def_preferred.json file in favor of def.json .SH CFENGINE CFEngine provides automated configuration management of large-scale computer systems. A system administrator describes the desired state of a system using CFEngine policy code. The program \fBcf-agent\fR reads policy code and attempts to bring the current system state to the desired state described. Policy code is downloaded by \fBcf-agent\fR from a \fBcf-serverd\fR daemon. The daemon \fBcf-execd\fR is responsible for running \fBcf-agent\fR periodically. .br Documentation for CFEngine is available at https://docs.cfengine.com/. .SH PROMISE THEORY CFEngine is built on principles from promise theory, proposed by Mark Burgess in 2004. Promise theory is a model of voluntary cooperation between individual, autonomous actors or agents who publish their intentions to one another in the form of promises. A promise is a declaration of intent whose purpose is to increase the recipient's certainty about a claim of past, present or future behaviour. For a promise to increase certainty, the recipient needs to trust the promiser, but trust can also be built on the verification that previous promises have been kept, thus trust plays a symbiotic relationship with promises. .br For an introduction to promise theory, please see http://arxiv.org/abs/0810.3294/ .SH AVAILABILITY cf-serverd is part of CFEngine. .br Binary packages may be downloaded from https://cfengine.com/download/. .br The source code is available at https://github.com/cfengine/ .SH BUGS Please see the public bug-tracker at https://tracker.mender.io/projects/CFE/. .br GitHub pull-requests may be submitted to https://github.com/cfengine/core/. .SH "SEE ALSO" .BR cf-promises (8), .BR cf-agent (8), .BR cf-serverd (8), .BR cf-execd (8), .BR cf-monitord (8), .BR cf-runagent (8), .BR cf-key (8) .SH AUTHOR Mark Burgess and Northern.tech AS
