Ah, well, pretty much all of the xfstests assume the ability to write
into the file system.  So it may be a while before using xfstests will
make sense for BeFS.

That's all which is necessary for xfstests --- the idea is that the
test will make various changes to the file system, and then
correctness is checked both by whether the expected output is printed
as the test probes changed the file system state, and by the
consistency checker confirming that the file system is in a consistent
sane state after each test completes.

I assume you mean write support in the above paragraph.  :-)
