Not sure if I agree. Using 2 or more disks with swap partitions causes
linux to effectively use those partitions with striping (RAID 0), thus
1GB+1GB=2GB with no redundancy. The point of having RAID 1 is so your
system doesn't go down if one disk fails. Suppose you exhaust RAM and
go into swap and that disk fails. You have just lost virtual RAM.
Crash. That's why I also put my swap on RAID 1.
