- <para><filename>systemd-getty-generator</filename> is
- a generator that automatically instantiates
- <filename>serial-getty@.service</filename> on the
- kernel console <filename>/dev/console</filename> if
- that is not directed to the virtual console
- subsystem. 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>
