+  <ul class="incremental">
+    <li>
+      Huge variety of disk drivers, net drivers and filesystems that
+      may be needed to mount root
+    </li>
+    <li>
+      Generic kernel shouldn't have all these built-in
+    </li>
+    <li>
+      Root might also need RAID, LVM, dm-crypt, which generally need
+      to be configured by userland
+    </li>
+    <li>
+      Kernel needs a way to load modules and run scripts but
+      it can't read them from the root filesystem
+    </li>
+    <li>
+      Solution: boot loader provides a bundle of files to the
+      kernel
