Thanks for your information . I will get in touch with Per.

We can add some option that the user could select where to install .

It is a good idea. Originally i just think about the full installation
in MTD, now it seems like adding some option is more suitable .
During the installation , the kernel only recognize the whole storage
of MTD flash. But if the user install the Debian more than once,
there must be some useful files in the MTD which he do not want to be erased.
So there should be some options that the user can configure the size of MTD
to be installed, select where to be installed (like above /root in MTD,
other remain disk) and make a filesystem in the MTD like jffs2. But i do not
know whether the partman-parittioning support making a filesystem in the
MTD, or should we add some tools to do this work.
