This is weird. I don't think my ubinized image contains 2 UBIFS volumes :|

[rootfs]
# Volume mode (other option is static)
mode=ubi
# Source image
image=root.squashfs
# Volume ID in UBI image
vol_id=0
# Allow for dynamic resize
vol_type=dynamic
# Volume name
vol_name=rootfs

[rootfs_data]
# Volume mode (other option is static)
mode=ubi
# Volume ID in UBI image
vol_id=1
# Allow for dynamic resize
vol_type=dynamic
# Volume name
vol_name=rootfs_data
# Autoresize volume at first mount
vol_flags=autoresize
vol_size=1MiB

I'll try to pick Tanya's patch and try again.
