Can't change root password on OpenWrt because of read-only file system

Hi Seeed support folks… Surely having to take 15 steps to refresh the OS is not how this is supposed to work… Can you fix the image you pre-install so that /etc isn’t on a read-only file system? (This is still happening, and I just received my new mini-router via DHL today.)

I love Seeed Studio, but I didn’t expect to have to rebuild the router to make it work. You guys usually have a better user experience!
