PRODUCT_TAPE parameter in image.data file

I found this out the hard way and haven't found it yet in the official documentation.

In a file generated by mkszfile(1), the value of PRODUCT_TAPE is set to "no". If you want to create a NIM image_data resource from this file and use it to install BOS, the value needs to be changed to "yes". Otherwise the BOS installation will bomb out in the initial stages (when copying CuDv to disk after creating logical volumes and filesystems).

To find this out I had to set BOSINST_DEBUG to "yes" in the bosinst.data file and examine the saved console output.
