+Subject: [PATCH] systemd Fails to parse boolean value.
+
+My host is installed with a Rocky Linux 9.x
+It should be the same with other distros.
+
+When PCSC is started, I can observe the following in /var/log/messages:
+```
+...
+Dec 05 16:22:43 Host-9A38CE systemd[1]: /usr/lib/systemd/system/pcscd.service:32: Failed to parse boolean value, ignoring: identity
+                                                                                  ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
+...
+```
+
+This comes from the following line, in pcscd.service:
+```
+RuntimeDirectoryPreserve=true
+```
+
+When `true` is replaced by `yes`, the error is no more seen.
+By the way, the rest of pcscd.service is already using `yes`.
