I am losing OTA update. rootstock is solely for hacking on the image and porting purposes, even porters should eventually provide a system-image server for their ports so OTA upgrades can be offered. > > Where does come from system-image? How are they build?
the server on system-image.ubuntu.com pulls the files from cdimage and
assembles them into a proper image, generates the update delta against
the last available image for OTA and signs it ...
while rootstock-touch-install tries to mimic this process on your PC
there is no guarantee that the result will be 100% identical to an
install you did with ubuntu-device-flash.
