We repartition it because we're adding partitions.
We have one kickstart file that we use regardless of medium type. For SSDs, we overprovision and leave unused space at the end. Some brands of SSDs were failing before we did that. We don't need to overprovision hard drives.
You could remove the repartitioning and it would do the right thing for your use case.
Ah okay. It seems that my re-adds were failing on arrays that don't have a bitmap. I was testing it on small arrays that don't get a bitmap by default.
