  Modified files:
    libexec/ftpd         ftpd.c 
  Log:
  Deny attempts to rename a file from guest users if the policy
  says they may not modify existing files through FTP.
  
  Renaming a file is effectively a way to modify it.
  For instance, if a malicious party is unable to delete or overwrite
  a sensitive file, they can nevertheless rename it to a hidden name
  and then upload a troyan horse under the guise of the old file name.
