+systemd (257.4-3+apertis1) apertis; urgency=medium
+
+  * Sync from debian/trixie.
+  * Remaining Apertis specific changes:
+    - AppArmor: Add systemd-logind profile
+    - Disable systemd-journal-remote since it depends on libmicrohttpd-dev
+        which depends on GnuTLS (LGPL-3)
+    - Remove '-execdir +' usage for compatibility with rust-findutils
+        https://github.com/uutils/findutils/issues/6
+    - Inject -Wno-error=format-overflow -Wno-error=format-truncation in
+      debian/rules. In contrary to Debian, we use by default -Wformat-overflow=2
+      and -Wformat-truncation=2 in Apertis, but due to the use of -Werror this
+      package FTBFS with: "cc1: all warnings being treated as errors".
+      In order to avoid this error, we don't treat these warnings as errors.
