+
+Recent versions of live-config have a bug relating to automatic serial console
+logins (eg, on /dev/ttyS0). These affect headless systems like torouter.
+
+Previously, a "live-getty" boot flag was sufficient to enable such logins. At
+some point this broke, and now even custom versions of /etc/inittab which
+enable regular logins get mangled by the live-config script '0170-sysvinit'.

+
+As a work-around, the bundled /etc/inittab and script 9999-serial_console
+combined de-mangle the 0170-sysvinit changes and enable an automatic user login
+on /dev/ttySO after system boot.
