docs: // checkIfPathIsInAVolume checks if the path is in a volume. If it is, it
  // cannot be in a read-only volume. If it  is not in a volume, the container
  // cannot be configured with a read-only rootfs.

  // This is a no-op on Windows which does not support read-only volumes, or
  // extracting to a mount point inside a volume. TODO Windows: FIXME Post-TP5
