decrypt a luks volume with a keyfile on boot from grub

[Daklon]

Hi, i have install a debian jessie in my laptop, i create a lvm volume with /, /home, etc and a /boot partition outside. the i move this partition to the lvm volume and boot from it, everything it´s okay and it works.

The problema is that wen boot it ask me the passprase to load grub, and then, when grub loads the kernel, it ask me again the passprase.

I read that i can pass a key file to the initramfs to solve this, but where i see it, he uses mkinitcpio, and i can´´t find this package in the debian repos, it an arch package, also i tried this option http://askubuntu.com/questions/59487/ho ... -partition

But it askin me the passprase 3 times, and the third fails, the sistem starts, but i read the fail in the log.

anybody could help me? thanks
