 livecd-rootfs (2.544) UNRELEASED; urgency=medium
 
+  [ Steve Langasek ]
   * Properly fix the hard-linking of vmlinuz, taken astray by my misguided
     merge review.
 
+  [ Dimitri John Ledkov ]
+  * When calling snap-seed-parse append stdout to file, but redirect
+    stderr to stdout, thus unbreak autopkgtests.
