+# systemd unit overrides
+
+These are meant to be in `/etc/systemd/system/whatever.service.d/` and thus
+override the behaviour of the unit either in `/etc/systemd/system` or
+`/lib/systemd/system`.
+
+See `../*.d/` for services that either symlink here or other inspiration for
+using overrides.
+
+**_DON'T PLACE THESE IN ACTUAL `/etc/systemd/system/service.d` OR THEY MIGHT
+AFFECT ALL SERVICES CAUSING UNEXPECTED BEHAVIOUR!_**
