I'm working on something similar for the other targets and here
are my two cents on the topic:

I ended up using coreutils-sfdisk instead of parted for the simple
reason that parted is not part of OpenWrt's core package set.
However, I reckon that including parted is actually the nicer option.
Also note, that if you are intending to use this script as a part
of the ImageBuilder, you can use the "ptgen" tool.
If this is supposed to be a stand-alone installer for OpenWrt on
SD-cards, I don't get why it should be included in the source tree
at all.

Is there any specific reason why ext4 is used for r/w rootfs?
