I would like to construct a GPT disk image file, which I will later dd onto a real disk. I am not sure how to do this, and so would appreciate any guidance. Here is what I have found; please correct me if any of the following is incorrect.
- It seems that gpt will nicely label a file as if it were a disk and will add partitions as normal. - I am not sure how to access those partitions, as dkctl complains if given a file as the first argument. - vnconfig seems to want a file that corresponds to a single partition, not a partitioned disk. This suggests one potential strategy: - create a file for each partition - mount it with vnconfig and populate the filesystem - create a file for the disk image - label the disk image with gpt - dd each partition into the disk image with an appropriate seek= option to place it at the location of the partition Is this a correct procedure? Is it the best option? What would be needed to recognize wedges in a GPT disk image so this could be simplified (i.e., create the GPT file image and mount the wedges directly)? Any guidance is greatly appreciated. Thanks a lot. Cheers, Brook
