In addition to that question, i would like to ask if there's software that's available to (all at once in one program):

• set default swap partition mounted on startup, but with failback default emmc swap (so when i let's say set default swap to sd and either unmount it or screw the card or my card reader brakes, the n900 would be still bootable without changing anything)
• setting as many swap partitions as desired by user and automatic reswapping in user-specified time intervals in a manner that, when we have let's say 3 swap partitions, the "1" is used at first ("2" and "3" are inactive), then after reswap, the "2" is used ("1" and "3" are inactive) and then after next reswap only "3" is used, and then "1" again - so only one swap partition is used at once
• possibility to manually reswap to any available swap partition on demand

Is there any program capable of all these three at once? I have ereswap right now, but I also find it to be not what I really want.
