-  * PLEASE SUMMARIZE remaining Apertis changes
+  * Sync updates from Debian Bullseye. Remaining change:
+    - Re-mkdir /proc instead of umount if it is a symlink. In docker, the
+      TARGET/proc will be a symlink to /proc. And if the docker instance
+      is called with --privileged, it will umount the /proc of the whole
+      instance in setup_proc
