Re: rwd0a and label sector marked read-only

All partitions (except RAW_PART) are defined in the disklabel,
so it might be problematic to define behavior when
the disklabel is updated via a partition which is being changed.

Because it requires a proper procedure (DIOCWLABEL), not privilege?

Because the RAW_PART is always vaild even if there is no valid disklabel?
