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 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).

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