+<para>Shadow hard-codes the path to the passwd binary within itself, but
+it does it the wrong way. If no passwd binary is present before
+installing Shadow, it (wrongly) assumes that it will be at /bin/passwd,
+but then installs its own in /usr/bin/passwd. This will lead to strange
+errors about not finding /bin/passwd. To fix workaround this bug in
+Shadow, we'll create a dummy passwd file so that it gets hardcoded in
+the right place:</para>
