Just for the record, the original post doesn't actually mention anything about this being for the _root_ disk. I assumed that he had a second or subsequent disk that was to be used as a single volume, but wanted to reserve a small space for swap to improve performance by interleaving the swap over multiple physical disks. Using a single / partition on the root disk is almost always a bad idea, and I don't recommend it.
