Hi Roel,

Instead of this:

                   (device "/dev/sda3")
                   (mount-point "/")
                   (options "ssd")
                   (type "btrfs"))

Try this:

                 (mount-point "/")
                 (options "ssd")
                 (type "btrfs")
                 (title 'uuid)
                 (device (uuid "4dab5feb-d176-45de-b287-9b0a6e4c01cb")))

But do replace the UUID with your actual UUID.  I’ve copied this
straight from the manual and haven’t tested this myself as I’m using
mapped devices and don’t have a btrfs partition.
