+    <title>Description</title>
+
+    <para><filename>systemd-getty-generator</filename> is a generator that automatically instantiates
+    <filename>serial-getty@.service</filename> on the kernel console(s), if they can function as ttys and are
+    not provided by 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. If execution in a container environment is detected, it will instead
+    enable <filename>console-getty.service</filename> for <filename>/dev/console</filename>, and
+    <filename>container-getty@.service</filename> instances for additional container pseudo TTYs as requested
+    by the container manager (see <ulink url="https://systemd.io/CONTAINER_INTERFACE"><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/admin-guide/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink>
+    for more information on the <varname>console=</varname> kernel parameter.</para>
