I have quite an inconvenient setup (detailed at the bottom for completeness), and I can only access /boot when the sdcard is not mounted on the rpi. That said, each of the two lines I added to /etc/fstab looks like:

Code:

LABEL=xbian-usb-btrfs /var btrfs [copied/pasted options from root, except "subvol=var"] 0 0

I have formatted the usb stick with btrfs, giving the appropriate label (xbian-usb-btrfs), and created the two subvolumes, "var" and "usr".

I did both, in order, and the output didn't change in any case. Removing quite did not add any line to the output (is this expected?).

Right now, I cannot continue experimenting with mountall.conf nor the keyboard, due to my constrained setup. I will try a fresh re-install to access files under /etc, and will report here my findings. But I hope at least my (pseudo-)fstab can give you some hints if I'm doing anything wrong.

(A note about my setup, and induced constraints: I only have a rpi, and a macbook. So direct usb-keyboard access to the rpi is not doable. Moreover, macosx only reads the vfat /boot partition, and the sdcard reader of the mac is not available to virtual machines (e.g. to let a linux VM mount the btrfs) ...it's SO frustrating!)
