+    <li>
+      Flash devices (and thin-provisioned SANs) can be more efficient
+      if the filesystem 'discards' unused disk space
+    </li>
+    <li>
+      Requires support in hardware, driver, filesystem and any layered
+      device drivers - e.g. LVM, RAID (added in 3.7)
+    </li>
+    <li>
+      Must be explicitly enabled, but d-i doesn't do this by default
