+ <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://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/admin-guide/kernel-parameters.txt"><filename>kernel-parameters.txt</filename></ulink>
+ for more information on the <varname>console=</varname> kernel
+ parameter.</para>
