SYSTEMD-GETTY-GENERATOR(8)             SYSTEMD-GETTY-GENERATOR(8)

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

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

     DESCRIPTION
          systemd-getty-generator is a generator that automatically
          instantiates serial-getty@.service on the kernel console(s),
          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
          m[blue]Container Interfacem[][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
          m[blue]kernel-parameters.txtm[][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 m[blue]systemd for Administrators, Part XVI: Gettys
          on Serial Consoles (and Elsewhere)m[][3].
