You can just do that. On the other hand, partitions a to c (and d on x86)
have a special meaning (a is root, b is swap, ..). So if you want to
parition a "data disk", then using e and following is better.

You can do something like:

disklabel sd0 > mylabel
disklabel -R sd1 mylabel

That requires that these are disks with identical geometry.
You also may want to have meaningful 'disk' and 'label'
fields. None of that is ensured when you copy a label.
