In the old days, the performance expense of using a fie for swap instead of a partition mattered. These days, if you need swap, you can usually allocate it trivially as a file and avoid the partition management problems. This avoids the partitioning and re-partitioning and re-allocation madness common to folks who think that cutting your disk into tinier and tinier slices will somehow create space for the applications they care about. Been there, done that, have the T-shirt. I've thrown most subtle partitioning out the window and use separate partitionss only for applications that really need it, such as high-performance mail spools or proxy services for which the "noatime" setting provides a significant benefit.
