# Upgrade the version of Morph used on a Baserock distbuild network.
#
# This allows quickly testing a new version of Morph without having to fully
# build and deploy a new Baserock 'build' system. You should run the
# 'restart.yaml' playbook after this one.
#
# This is an Ansible playbook. Run with:
#
#   ansible-playbook -i distbuild-hosts use-latest-morph.yaml
#
# You will need a file named 'distbuild-hosts' describing your distbuild
# network.
