Because of this reason, we should ask ourselves whether we want to backport this to 19.07, so all (non-RC) released ath79-tiny images have 4k sectors, while we still can. Otherwise, with 20.xx having different sectors than 19.xx, users will be more confused than with us now changing behavior during rc-period. Best Adrian
