    pool: mac
    resource: mac-m4

Pool Repo Structure

The pool repo should have the following structure:

${pool}/
    claimed/
        .gitkeep
    unclaimed/
        .gitkeep
        ${resource}

There can be other files but this is the minimum required structure. The claimed directory is where the lock will push to on claim and the unclaimed directory is where the lock will push to on release. The unclaimed directory should contain a file with the name of the resource that is being locked. The file can be empty or contain any data. The claimed directory should contain a .gitkeep file to ensure that it is created in the repo. The unclaimed directory should also contain a .gitkeep file to ensure that it is created in the repo.
