What should I do with this apparently redundant swap partition?

view story

http://askubuntu.com – I have a machine running Ubuntu Server on an encrypted LVM, with an encrypted swap partition. After I unlock the LVM during boot, I get this message: The disk drive for /dev/mapper/<hostname>-swap_1 is not ready yet or not present. This stays up for twenty seconds or so, then I get the normal login prompt. Immediately after I log in, swapon -s shows that a different swap partition is active: Filename Type Size Used Priority /dev/mapper/cryptswap1 partition 2428924 0 -1 /etc/crypttab has no mention of &lt (HowTos)
