// xfs_quota tool can be used to assign a project id to the driver home directory, e.g.:
// echo 999:/var/lib/containers/storage/overlay >> /etc/projects
// echo storage:999 >> /etc/projid
// xfs_quota -x -c 'project -s storage' /<xfs mount point>

// In the example above, the storage directory project id will be used as a

// Then try to create a test directory with the next project id and set a quota
// on it. If that works, continue to scan existing containers to map allocated
