I'm thinking of using fuse to build a test harness for YAFFS and thought I'd
ask opinions before I went ahead.
YAFFS is pretty modular in that the OS-specific functions (VFS and mtd
interfacing) can be unplugged and replaced with other functions. This allows
the core "guts" to be built and tested in application space.
The pain with doing the testing in an application is that writing test code
etc takes a long time. I'd rather be able to do testing interactively from
bash etc, which leads to the idea of running YAFFS as a fuse application.
Any comments as to the sanity of this approach?
Can you do things like single step a fuse application without breaking the
kernel?
Thanx

Of course.
Another approach is to use UML, which gives a similar debugging
environment but without having to port your filesystem to userspace.
