+pppd: Fix creation of linkpidfile
+
+When pppd is run without "nodetach" or with "updetach", the linkpidfile is
+never created. The call to create_linkpidfile() is protected by a check for
+linkpidfile[0] but this is only filled in when create_linkpidfile() is called.
+
+This patch changes to code to allways uncondiationally call
+create_linkpidfile(), it originated from the Debian project.
