How do you change the LUKS filesystem password?

First, add a second key (password):
cryptsetup luksAddKey /dev/XXX
Then delete the original key
cryptsetup luksKillSlot /dev/XXX 0
You need to be careful to get the slot numbers correct. Use the luksDump option to see how things are setup on your system.
luksKillSlot does not work for me on Centos 5.6. luksDelKey does.
