retitle 337663 initramfs-tools does not load correct keymap
thanks

The original report complains that rescue shell has wrong keymapping.
This can be agreed to be a minor issue. However, no keymap being loaded
makes inputting complex cryptoroot passphrase with special characters
(especially ones not in the US layout) quite a challenge. 

Adding loadkeys and users selected keymap could be done in cryptsetup
hook scripts. However, since there seems to be users who want correct
keymap in other cases as well (the rescue shell), it might be worth 
implementing in initramfs-tools. If agree, I can provide a patch, if you
disagree, I'll go bug cryptsetup people.

Cheers,
Riku
