I really struggle to understand how root=/dev/sda should work. I've two partitions on the USB drive, where sda1 is actually the "/" [root]. Xbian handles this differently or it's btrfs thing?

Code:

cat /proc/cmdline

there you will see how kernel got the file changed/processed.

It still doesn't make any sense to me.

Terminal

according to the proc-filesystem, root is still "/dev/mmcblk0p2" but /dev/sda1 is found attached to the directory tree.

Trying out at the moment...
