+Subject: Bug#284382: ppp: linkpidfile is not created upon detachment
+From: <herbert@gondor.apana.org.au>
+
+Package: ppp
+Version: 2.4.2+20040428-2
+Severity: wishlist
+
+When pppd detaches from the parent normally, that is, without nodetach
+or updetach set, the linkpidfile is not created even when linkname is
+set.
+
+This is because the create_linkpidfile call in detach() is only made
+if the linkpidfile is filled in.  However, linkpidfile is never filled
+in until create_linkpidfile has been called.
+
+IMHO the call should be made uncondtionally in detach() since
+create_linkpidfile does its own check on linkname anyway.
+
+Please note that the version of pppd in woody always wrote the
+linkpidfile after detaching.  It did so in main() however.  That
+call has now been removed which is why I'm seeing this problem.
