Is there any way to resize root and data such that root expands/flattens when files and others are added/deleted? Such that I can make more space for the data partition. At the moment my partitions are built with minimal size and I expand them with gparted after I added them on the sd card. But if I put my device somewhere unreachable it would be very useful to have a way to expand and flatten portions on the fly.

It is said that btrfs supports such feature? Frankly I didn't try it out.
Yocto supports building out btrfs images. Maybe you can give it a try?
