Only one device of multidevice btrfs is decrypted in cryptroot

[Marek Dopiera]

Setup

Description: Ubuntu 14.04.1 LTS
Release: 14.04
cryptsetup:
  Installed: 2:1.6.1-1ubuntu1
  Candidate: 2:1.6.1-1ubuntu1
  Version table:
 *** 2:1.6.1-1ubuntu1 0

        100 /var/lib/dpkg/status

The setup is 2 LUKS encrypted partitions on top of which is btrfs setup as RAID 1. The problem is that only one device is decrypted in the generated initramfs image.

Reason for failure
---
I debugged the problem myself and the reason is:
- there is no LVM-like code in the initramfs hook to include others as well

Solution
---
The solution is to make the hooks aware of other btrfs devices.

Workaround
---
Manually specify other devices as resume devices.
