+systemd (241-7~deb10u6co2) apertis; urgency=medium
+
+  * Add /usr to non-unmountable list.
+    For Apertis we don't support `/usr` being a seperate partition, the only time
+    `/usr` is on a mountpoint is when using ostree images (where it is a bind mount
+    and which use a merged-usr layout). So also add `/usr` to the list of paths that
+    are considered unmountable even with split-usr support enabled in systemd.
