<li><p>If the required rootfs already exists under '''<span class="mark">external/cache/rootfs</span>''', then compiling rootfs again will directly skip the compilation process and will not restart the compilation. When compiling the image, it will also go to '''<span class="mark">external/cache/rootfs</span>''' to find out whether it has If there is rootfs available in the cache, use it directly, which can save a lot of download and compilation time.</p></li></ol>
