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. Finally, it will instantiate
       container-getty@.service instances for additional container pseudo TTYs
       as requested by the container manager (see Container Interface[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 kernel-parameters.txt[2] for more
       information on the console= kernel parameter.

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