It didn't make it to tech-kern... :-)

I'm not sure. I don't think there had been much thought about it. I think
that most of the filesystems we have now would probably be poor choices
for a flash system, but that's my opinion. :-) Assuming you mean
read/write. If you went with some sort of r/o ramdisk for your root, and a
memory disk for your r/w areas, that would work. What to do about
permanent, modifiable storage, I'm not so sure about.

Take care,
