fix the initramfs issue and allow Debian Wheezy to boot from the btrfs RAID1

For this to work, the filesystem must be specified by UUID on the kernel
command line from grub, e.g.


   root=UUID=57f36137-36ec-4f6c-a76e-c72c86330cc2

and should also be specified by UUID in /etc/fstab, e.g.


# cat /etc/fstab
UUID=57f36137-36ec-4f6c-a76e-c72c86330cc2   /   btrfs  defaults 0 1
/dev/sda1 /boot  ext4  defaults 0 2
/dev/sda2  none swap sw 0 0
