ProFtpd настройка директорий

What if you want to prevent a certain directory from being deleted, but you do want to allow sub-directories in that directory to be deletable? Using two <Directory> sections with <Limit> sections, you can do this, e.g.: 
  <Directory /path/to/dir>
    <Limit RMD XRMD>
      DenyAll
    </Limit>
  </Directory>

  <Directory /path/to/dir/*>
    <Limit RMD XRMD>
      AllowAll
    </Limit<
  >/Directory>
 Note the trailing "/*" suffix in the second <Directory> section; this means that the second <Directory> section configuration applies to the sub-directories, but not to the parent directory itself (which is covered by the first <Directory> section).
