a generator that automatically instantiates
<code class="filename">serial-getty@.service</code> on the
kernel console <code class="filename">/dev/console</code> if
that is not directed to the virtual console
subsystem. It will also instantiate
<code class="filename">serial-getty@.service</code> instances
for virtualizer consoles, if execution in a
virtualized environment is detected. Finally, it will
instantiate
<code class="filename">container-getty@.service</code>
instances for additional container pseudo TTYs as
requested by the container manager (see <a class="ulink" href="http://www.freedesktop.org/wiki/Software/systemd/ContainerInterface/" target="_top"><code class="filename">Container Interface</code></a>). 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 <code class="varname">console=</code> to get
both kernel messages and a getty prompt on a serial
TTY. See <a class="ulink" href="https://www.kernel.org/doc/Documentation/kernel-parameters.txt" target="_top"><code class="filename">kernel-parameters.txt</code></a>
for more information on the
<code class="varname">console=</code> kernel parameter.</p><p><code class="filename">systemd-getty-generator</code>

gettys you may find in <a class="ulink" href="http://0pointer.de/blog/projects/serial-console.html" target="_top">systemd
