Hi,
My raspberry configuration is booting from an external usb disk with btrfs filesystem.
When I want to upgrade packages trough xbian-config I always obtain an error on DPkg::Pre-Invoke
right when the snapshot should be taken.
The error is "The filesystem argument list is empty"
After debugging I figure out what happend: The argument of the script btrfs-auto-snapshot is empty.
That because I don't have the root volume.
Here is my findmnt -n output
FYI
xbian@raspberrypi ~ $ sudo btrfs-auto-snapshot list

Could someone tell me how to create (if possible) these missing volumes, in order to make upgrade working without commenting the 06xbian-btrfs script?
Thank you
