 fdesc implements /dev/fd. It should have a man page; that is a bug.
 (There is actually an fd(4) page for /dev/fd, but it makes no mention
 of fdesc. This also raises the question of whether the floppy driver
 has a man page.)
 
 It should also accept chown/chmod operations that do not actually
 change the attributes of its objects, instead of just failing
 unconditionally. I'm pretty sure that's what it's doing and that it's
 what causes the behavior you're seeing.
