It will also instantiate <filename>serial-getty@.service</filename> instances for virtualizer consoles, if execution in a virtualized environment is detected. Finally, it will instantiate <filename>container-getty@.service</filename> instances for additional container pseudo TTYs as requested by the container manager (see <ulink url="http://www.freedesktop.org/wiki/Software/systemd/ContainerInterface/"><filename>Container Interface</filename></ulink>). This should ensure that the user is shown a login prompt at the right place, regardless of which environment the system is started in. For example, it is sufficient to redirect the kernel console with a kernel command line argument such as <varname>console=</varname> to get both kernel messages and a getty prompt on a serial TTY. See <ulink url="https://www.kernel.org/doc/Documentation/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink> for more information on the <varname>console=</varname> kernel parameter.</para> <para><filename>systemd-getty-generator</filename> implements <citerefentry><refentrytitle>systemd.generator</refentrytitle><manvolnum>7</manvolnum></citerefentry>.</para> <para>Further information about configuration of gettys you may find in <ulink url="http://0pointer.de/blog/projects/serial-console.html">systemd for Administrators, Part XVI: Gettys on Serial Consoles (and Elsewhere)</ulink>.</para> </refsect1> <refsect1> <title>See Also</title> <para> <citerefentry><refentrytitle>systemd</refentrytitle><manvolnum>1</manvolnum></citerefentry>, <citerefentry project='man-pages'><refentrytitle>agetty</refentrytitle><manvolnum>8</manvolnum></citerefentry> </para> </refsect1> </refentry>
