I did a patch to allow armbian build system produce image with root on xfs filesystem.

Kernel should have build-in filesystem support, and `RELEASE` have to contain required filesystem utilities. Then all need to be done — add filesystem to build process. Patch for builder attached.

Then image have to be build with separate /boot filesystem.

command should look like

./compile.sh BOARD=rockpi-4a BRANCH=current RELEASE=focal BUILD_MINIMAL=no BUILD_DESKTOP=no KERNEL_ONLY=no KERNEL_CONFIGURE=yes BOOTSIZE=250 ROOTFS_TYPE=xfs
