If the system swaps, a read error on the swap device will panic the
system.

Although swap data is always transient and after a reboot generally not
interesting anymore, I ALWAYS put swap on a mirror/raid3/raid5/raidz
just to make sure the system survives a read error, especially with
remote systems.
