As I said at the HUG, I want to get the non-swift-FS specific tests that do
things like run Pig jobs against any FS in, though I also need a home for
some very swift-specific partitioned file tests.

not in filesystems. If you look how long it took ext4 to be implemented and
then adopted, you can see that nobody put data they cared about on it until
they were happy that what you put on write() came back on a read() [and
stat() returned the amount of data, [seek(X);read()] returned the byte at
offset X and other little details that those of us writing tests for the
filesystem APIs care about]
