Comment 6 for bug 238163

well, wait a minute. After rereading the bug description, I come to the following conclusion:

- you have an encrypted root and want to use a keyfile instead of a password.
- In your /etc/crypttab you put the keyfile in /etc/luks_passwd.
- the initramfs has no possibility to decrypt the key in /etc/luks_passwd because it would need to have that key in advance
- the message is warning exactly because of this issue.

If you want to get the keyfile from a removable device, please about the passdev script from the cryptsetup package in intrepid in /usr/share/doc/cryptsetup/README.initramfs.gz
