The Sun disklabel lives within the first 64 kByte (as I remember from
memory) of the disk. Sun UFS excludes this area from being used in purpose
not to destroy the label. If you are placing anything else on the disk that
is not aware of the necessity of this workaround, then you should avoid
including the first cylinder ("0") into the slice (I had similar experience
on Solaris with placing a Sybase device into the first slice),
