ah. success! looks like it's just that gnu 'mv' and 'ln' are waaaay too
smart for their own good. you got me thinking... what are 'mv' and 'ln'
doing lstat() for anyway?
so I wrote a few lines of C and stdio's rename() "just works" on the
client, even when the OST is disabled (as it damn well should).
happily python's os.rename() works too ('cos I am lazy)
whoo! no need to mess with the MDT. that's a relief.
