+              hash: 02d42d3cc887fb761da348f86bf5e13f1dacaeb2
+              body: >
+                At this moment the kexec initrd script just takes the original
+                kernel
+
+                command line, replaces root with UUID and removes bootloader
+                args.
+
+
+                We have found at least one use-case (on the Pi4 and firmware
+                GPIOs),
+
+                where a different initrd script needs to pass extra arguments
+
+                to the kexec'd kernel. With this patch it will append the
+                contents
+
+                of the KEXEC_EXTRA_ARGS variable to the kernel command line.
