By changing those factors different deployment patterns can be triggered though Jenkins. We used below Mcollective command to change factors in all agent machines. This helps us to trigger deployments though Jenkins. *mco shell run 'rm /etc/facter/facts.d/deployment_pattern.txt;mkdir -p /etc/facter/facts.d; echo "deployment_pattern=pattern1" >> /etc/facter/facts.d/deployment_pattern.txt'* So if you can consider about factors to hold high level deployment options then that would be very continuous delivery friendly option.
