Name
systemd-getty-generator - Generator for enabling getty instances on the consoleSynopsis
/lib/systemd/system-generators/systemd-getty-generator
Description
systemd-getty-generator is a generator that automatically instantiates [email protected] on the kernel console(s), if they can function as ttys and are not provided by the virtual console subsystem. It will also instantiate [email protected] 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 [email protected] instances for additional container pseudo TTYs as requested by the container manager (see \m[blue]Container Interface\m[]\&\s-2\u[1]\d\s+2). 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.txt\m[]\&\s-2\u[2]\d\s+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[]\&\s-2\u[3]\d\s+2.
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.
