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

`/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(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`). 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` 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).

## Kernel Command Line

`systemd-getty-generator` understands the following kernel-command-line 7 parameters:

`systemd.getty_auto=`

  this options take an optional boolean argument, and default to yes. The generator is enabled by default, and a false value may be used to disable it.

## Environment

`$SYSTEMD_GETTY_AUTO`

  This variable takes an optional boolean argument, and default to yes. The generator is enabled by default, and a false value may be used to disable it.
