i mean do the update somehow on the fly without removing the card from a running system, on the pc build a new rootfs and instead of removing the card, and do the copying on the pc, do this directly on the dk board. in principle it should be possible, i just need the 'magic' commands/scripts, or even have this new rootfs in ram on some ram drive
e.g. scp the new rootfs, then chroot to it, somehow
