# ansible-playbook -i dummy-ansible-hosts contrib/splitup.yml \
#   --tags split --extra-vars github=mhubig/ansible
#
# ansible-playbook -i dummy-ansible-hosts contrib/splitup.yml \
#   --tags update --extra-vars github=mhubig/ansible
#
# To point to a specific role, ie: ceph-mon just run with "-e roles=ceph-mon"
#
