Minimal linux partitions
Contrary to popular belief, you can setup linux with ONE partition, root, or /. You don't strictly need a swap partition. It might be a really bad idea to not have one, but it is not required. I have one server that has been running for a few years with no swap partition. If you are going to leave out the swap partition, you really had better know what you are doing.
