+  fix: a failing user directory or token database no longer leaves the tunnels down.
+
+  * vpn-router-setup brings up strongSwan and WireGuard before it provisions
+    the user directory and the token database. A failure of either no
+    longer stops the other steps; setup reports it and fails at the end.
