Details

Description:
An encrypted root partition on an cf card attached via usb is correctly encrypted (as seen by using break=y), but it can't be mounted unless rootfstype=btrfs is given as kernel parameter. The message is "unable to mount root fs on device dev(254,0)", the result a kernel panic. It might be that the change of the btrfs format in kernel 2.6.31 from testing is part of the problem.

Additional info:
* kernel 2.6.31.1-1 from testing
* klibc 1.5.15-3

Steps to reproduce:
Perhaps a btrfs root partition is enough, perhaps other factors play a role, too...
This task depends upon

@Thomas: is this relevant to the new busybox-based initramfs? If not then it's "Won't fix"

If I ever get things to build, yes, blkid should also support btrfs. Given btrfs is not safe for production use, appending rootfstype= is not too much to ask of someone willing to experiment.
