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

SYNOPSIS
       /usr/lib/systemd/system-generators/systemd-getty-generator

DESCRIPTION
       systemd-getty-generator is a generator that automatically instantiates serial-getty@.service on the kernel console /dev/console if that is
       not directed to the virtual console subsystem. It will also instantiate serial-getty@.service instances for virtualizer consoles, if
       execution in a virtualized environment is detected. 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 kernel-parameters.txt[1] for more information
       on the console= kernel parameter.

       systemd-getty-generator implements the generator specification[2].

       Further information about configuration of gettys you may find in systemd for Administrators, Part XVI: Gettys on Serial Consoles (and
       Elsewhere)[3].
