None that I'm aware of yet.  But for the future, there will be media (not
necessarily disks) with like an 8K sector size.  Note that sector size > cpu
PAGE_SIZE will break Linux badly anyhow.

sector_size.

Yes, hardware defines what its sector_size is.  CD-ROMs use 2048 bytes, most
disks use 512 bytes.  This *does* mean you can't simply dd from a disk with
one sector_size to one with a different size.  Oh well.

This isn't critical BTW, just an observation that parted always uses 512,
and GPT could be more flexible.

Thanks,
Matt
