And people wonder why I recommend putting the swap last, just before a DOS partition. The reason is to allow you to back up your DOS (for which there is good, fast, reliable backup available, much as it pains me to say it), move the DOS partition, and simply blow the disk label to increase your swap. Restore the DOS garbage to the DOS partition. What we really need is the ability to swap to a file (any file -- say an NFS mounted one, for instance) and get rid of the idea of a swap partition altogether. Then you make a default swap file out of a bunch of contiguous file system blocks; if you let it grow, you pay for it being discontinuous then; at least you don't have to reinstall.
