systemd-getty-generator - Generator for enabling getty instances on the console

       systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the
       kernel consoles, if they can function as ttys and are not provided by the virtual console subsystem. It
       will also instantiate serial-getty@.service instances for virtualizer consoles, if execution in a
       virtualized environment is detected. If execution in a container environment is detected, it will instead
       enable console-getty.service for /dev/console, and container-getty@.service instances for additional
       container pseudo TTYs as requested by the container manager (see ContainerInterface[1]). 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 console= to get both kernel messages and a getty prompt on a serial TTY. See Thekernel'scommand-lineparameters[2] for more information on the console= kernel parameter.

       systemd-getty-generator implements systemd.generator(7).

       Further information about configuration of gettys can be found in systemdforAdministrators,PartXVI:GettysonSerialConsoles(andElsewhere)[3].

$SYSTEMD_GETTY_AUTO
           This variable takes an optional boolean argument, and default to yes. The generator is enabled by
           default, and a false value may be used to disable it.

           Added in version 250.

       systemd-getty-generator understands the following kernel-command-line(7) parameters:

       systemd.getty_auto=
           this options take an optional boolean argument, and default to yes. The generator is enabled by
           default, and a false value may be used to disable it.

getty.ttys.serial, getty.ttys.container
           These system credentials may be used to spawn additional login prompts on selected TTYs. The two
           credentials should contain a newline-separated list of TTY names to spawn instances of
           serial-getty@.service (in case of getty.ttys.serial) and container-getty@.service (in case of
           getty.ttys.container) on.
