A bit of both I guess. As I'm developing a platform which will be used
for proprietary products, so I have to make sure we have the freedom to
keep the application closed. We could always get a license for YAFFS,
but I'd rather use something without the need for licensing. Second, it
seems YAFFS is quite a bit more heavyweight than UFFS. As we're rather
tight on ROM/RAM, I'm looking for a really lightweight FS, and UFFS
seems to fit the bill rather nicely.

I was thinking about this too, but again, I think UFFS is a lot more
lightweight than UBI/UBIFS.
The nice thing about eCos is it's configurability. More options cannot
really hurt IMHO as long as share code and subsystems (NAND) wherever
