I have no idea about your first question. You may
want to ask it again.
Regarding summary support I have never been able to
make a jffs2 filing system that used summary support
with the mkfs.jffs2 tool that worked. I create the
filing system with summary support on an empty chip
and then transfer the files. Please let me knhwo if
you get it to work with the mkfs.jffs2 tool.
