+
+  [ Steve Langasek ]
+  * Deduplicate snaps between squashfs layers on classic:
+    - Consolidate canary layers to merge 'classic' back into 'standard'
+    - Reset /var/lib/snapd in the upper layers before calling snap
+      prepare-image
+    - No need to use rsync in hooks now to avoid file duplication since layer
