+Subject: [PATCH 1/2] legacy.conf.in: Don't create symlink README in this file
+
+Commit 6fe23ff31c0 changed README to an symlink to README.logs, and
+install README.logs under systemd doc dir.
+
+But for OE, systemd doc dir is splited into package systemd-doc, when it
+is not installed on the target, there will be an dead link:
+Eg:
+root@intel-x86-64:/var/log# ls -l README
+lrwxrwxrwx 1 root root 39 Jun 20 08:57 README -> ../../usr/share/doc/systemd/README.logs
+root@intel-x86-64:/var/log# ls -l ../../usr/share/doc/systemd/README.logs
+ls: cannot access '../../usr/share/doc/systemd/README.logs': No such file or directory
+
+So remove this symlink from package systemd
+
+Upstream-Status: Inappropriate [oe specific]
