What's the reason for the rm -fr; mkdir -p in the update script?  I
don't see how we'd be unintentionally generating cruft in these
directories if we were to just overwrite files instead of removing the
directory and repopulating it.  I'll get the kernel fixed soon, but I'm
tempted to add vfio and drop the expunge of the directory at the same
time.  Thanks,
