+  * Backport changes to fix kdump functionality. LP: #828731.
+    - debian/kdump.initramfs: call /usr/bin/makedumpfile via a chroot command,
+      so that if makedumpfile is statically linked, we get proper library
+      resolution.  Thanks to Louis Bouchard <louis.bouchard@canonical.com> for
+      the patch.  LP: #785425.
+    - debian/kdump.initramfs: handle the possibility that /usr, /boot, or
+      /var is on a separate filesystem and needs to be manually mounted before
+      calling makedumpfile.  LP: #828731.
+    - Depend on makedumpfile, without which the initramfs script doesn't work.
+    - Fix an unnecessary bashism.
+    - Only install the kdump initramfs script and depend on makedumpfile on
+      architectures that makedumpfile supports.
