SYSTEMD-GETTY-GENERATOR(8)				      systemd-getty-generator					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 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].
