Wow, that is really great. Right now with the FFS2 stuff I am using we
have to have a FFS2 module installed on the host to populate the file
system image, it kind of sucks in alot of ways.

Is the on flash structure documented? I need to write a simple read-only
driver for bootloaders. (see the boot stuff in MTD CVS, if it is still the
things I cooked up..)
There is a very good chance I am going to ditch FFS2 and just use JFFS for
all our products, I don't really like writing filesystem code and JFFS
sounds all round better than what MS came up wtih [FFS2 has inherent
consistency issues] :>
