technically, swap is never on memory. swap is memory written to the disk (when data is in memory it is either used or cache) what you wrote is the correct way to create a partition in memory (i do the same for my swap, the difference is my disk is one 1 gb / and 95 Gb cgd disk but it is just for the fun of doing it, i am not yet that paranoid...) i suggest you to keep the swap entry. on bsd systems it wont be used that much, and when it does you have usually trouble on your hands (your mileage and size of flames coming from the server might vary). if you are worried and paranoid, you can create a partition, mounted on each boot with a random key for your swap and tmp and that key will be forgotten on each reboot and a new random one used. keep the swap entry. the /tmp one is good and that's how you create one to put your /tmp in memory. -- unzip ; strip ; touch ; grep ; find ; finger ; mount ; fsck ; more ; yes ; fsck ; umount ; sleep
