My problem is with both ubuntu 32 bit lucid on an intel atom powered netbook and on an amd64 bit linux mint maya.

The issues are the same using mkfsyaffs2image or mkyaffs2 either pre compiled or self compiled.

The idea is to create a system image as part of a rom, the page size and spare are correctly set- but both systems create massively oversized system.img

can anyone help,or do i need to report a bug? either to ubuntu or developer?
