So how do I initialise /dev/hda2 for this to work? Am I expected to
run the decrypt_derived script and take the output as keyphrase?

If I do that, I get:

lapse:~# cryptsetup luksFormat /dev/hda2                               #[1,376]

This will overwrite data on /dev/hda2 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter LUKS passphrase: <the hash output from /root/decrypt_derived cr_hda5>
Verify passphrase: <the hash output from /root/decrypt_derived cr_hda5>
Command successful.
lapse:~# /etc/init.d/cryptdisks start                                    #[377]
Starting remaining crypto disks... cr_hda5(running) cr_hda6(running) cr_hda7(running) cr_hda8(running) cr_hda9(running) cr_hda2(starting)-e 
 - The device /dev/hda2 contains a valid filesystem type crypto_LUKS.
