Thanks for forwarding this. parted should only be clobbering these extra
sectors when a new disklabel is applied (eg. mklabel in the ui) which, I
think, is the appropriate thing to do.

If you are operating on an existing disklabel and want to preserver a
boot loader in the space before the 1st partition you shouldn't be
calling ped_disk_new_fresh(). If you are creating a new disklabel then
any boot loader code should be installed after partitioning.

I don't think parted needs any changes.
