bug#32313: Failed to boot after reconfiguring with a btrfs drive.

[Brendan Tildesley]

I have a second btrfs drive that I normally manually mount as /mnt/1tb.
I decided to add it to my system config and it when I reconfigure it
mounts the drive correctly, but when I reboot I get the error:

WARNING: failed to open /dev/btrfs-control, skipping device
registration: no such file or directory

ERROR: there are 1 errors while registering devices

File system check on /dev/sda1 failed; spawning Bourne-like REPL

Here is my system config:
