pcd_system.yml

---
##
# prepare|configure|deploy systems
#
#  1. (optionally) limit the hosts via --limit, and tasks via --tags 
#
#  e.g. ansible-playbook -i inventory/my.hosts pcd_system.yml \
#          --limit=nashville-app-1.iceburg.net --tags=configure 
#    
#  + `prepare` tasks typically handle ONE-TIME prerequisites such as setting
#    the hostname, preparing ssh public key authentication and root user's key,
#    ensure /etc/ansible metadirs, &c.  
#    
#  + `configure` tasks typically execute more often, whenever
#    configuration changes are made. E.g. change swap size
#
#  + If no tags are passed, all tasks will be executed.
