+ <td>Adds the specified directory or directories to the directory list that rEFInd scans for EFI boot loaders when <tt>scanfor</tt> includes the <tt>internal</tt>, <tt>external</tt>, or <tt>optical</tt> options. Directories are specified relative to the filesystem's root directory. You may precede a directory path with a volume name and colon, as in <tt>somevol:/extra/path</tt>, to restrict the extra scan to a single volume. A volume number, preceded by <tt>fs</tt>, can be used for volumes that lack names, as in <tt>fs1:/extra/path</tt>. If you don't specify a volume name or number, this option is applied to <i>all</i> the filesystems that rEFInd scans. If a specified directory doesn't exist, rEFInd ignores it (no error results). The default value is <tt>boot</tt>, which is useful for locating Linux kernels when you have an EFI driver for your Linux root (<tt>/</tt>) filesystem.</td>
