178 <warning>
179 <para>If the recommended dependency <xref linkend="freetype2"/> is not

181 if <command>grub-mkfont</command> is not built, or the unicode font
182 data is not avaliable at the time GRUB is built, GRUB won't install
183 any font for the boot loader. The GRUB boot menu will be displayed
184 using a coarse font and the early stage of kernel initialization will be
185 in <quote>blind mode</quote> &mdash; you can't see any kernel messages before
186 the graphics card driver is initialized. It will be very difficult to
