Steps to extract playbookconfig from starlingx/config

gistfile1.txt

* Put current oslo.tools somewhere:
  export OSLO_TOOLS=$HOME/src/openstack/oslo.tools

* Make a workspace:
  mkdir tmp; cd tmp

  # Get the source repo
  git clone https://opendev.org/starlingx/config.git

  # Get the original ansible-playbooks repo from Gerrit for comparison
  git clone https://opendev.org/starlingx/ansible-playbooks.git ansible-playbooks-take-1

  # Get the split script (if necessary)
  wget -N https://raw.githubusercontent.com/dtroyer/home/master/bin/split-repo.sh

* We want to split at a specific commit before HEAD so make a working branch in the source repo at that point:
  branch=work
  commit=feba4d21cbdd

  cd config
  git checkout -b $branch
  git reset --hard $commit
  cd ..

* Make a split map:
  config/^CONTRIBUTORS.wrs|CONTRIBUTORS.wrs
  config/^README.rst|README.rst
  config/^.gitignore|.gitignore
  config/^centos_iso_image.inc|config/centos_iso_image.inc
  config/^centos_pkg_dirs|centos_pkg_dirs
  config/^playbookconfig|playbookconfig

* Run split on a specific commit:
  ./split-repo.sh playbookconfig.map $branch

* Clean up new repo:
  cd ansible-playbooks

  # rename work branch to master
  git branch -m master

* Pull in commits from old ansible-playbooks:
  git remote add old ../ansible-playbooks-take-1
  git fetch old

  # .gitreview
  git cp 4266117883109c80ed4d18c73bd390f1cc5f690d

  # tox & zuul
  git cp 6bef82acb56d88058e5089c90fe300c273b91719

* Make changes not found in any commit:
  cp ../ansible-playbooks-take-1/CONTRIBUTORS.wrs \
    ../ansible-playbooks-take-1/LICENSE \
    ../ansible-playbooks-take-1/README.rst \
    ../ansible-playbooks-take-1/centos_iso_image.inc \
    ../ansible-playbooks-take-1/centos_pkg_dirs \
    ../ansible-playbooks-take-1/tox.ini \
    .

  # We left LICENSE out of the filter list because it matched a bunch of files...
  git add LICENSE

  git commit --author="Tee Ngo <Tee.Ngo@windriver.com>" -asm "Clean up repo import"

* Compare old and new:
  diff -u -r -w ../ansible-playbooks-take-1/playbookconfig playbookconfig
