  Modified:    sys/kern  vfs_syscalls.c
  Log:
  Dont allow directories to be link()ed or unlink()ed, even for root
  (returns EPERM always, the errno is specified by POSIX).
  
  If you really have a desperate need to link or unlink a directory, you
  can use fsdb. :-)
  
  This should stop any chance of ftpd, rdist, "rm -rf", etc from
  bugging out and damaging the filesystem structure or loosing races
  with malicious users.
