I found jffs and a couple other journalling approaches to implimenting
a block device underneath a Unix or DOS filesystem, but they all seemed
way too big/complex when my filesystem isn't going to be more than a few
hundred KBytes and will be rarely written to. For now, I'm going to try
to use a ROM filesystem and have users download the whole directory
tree when a file changes.
\x18It could be worse, I could ask them to link the files as data with the
application code and eCos.
Maybe in phase II (AKA: the list of things that will never get done)
I'll come up with a simple flash filesystem for my situation: writes
are rare and are allowed to block reads for a long time (several seconds).
