31 | <para><filename>systemd-getty-generator</filename> is a generator that automatically instantiates |
32 | <filename>serial-getty@.service</filename> on the kernel console(s), if they can function as ttys and are | |
33 | not provided by the virtual console subsystem. It will also instantiate | |
34 | <filename>serial-getty@.service</filename> instances for virtualizer consoles, if execution in a | |
35 | virtualized environment is detected. If execution in a container environment is detected, it will instead | |
36 | enable <filename>console-getty.service</filename> for <filename>/dev/console</filename>, and | |
37 | <filename>container-getty@.service</filename> instances for additional container pseudo TTYs as requested | |
38 | by the container manager (see <ulink url="https://systemd.io/CONTAINER_INTERFACE"><filename>Container | |
39 | Interface</filename></ulink>). This should ensure that the user is shown a login prompt at the right | |
40 | place, regardless of which environment the system is started in. For example, it is sufficient to | |
41 | redirect the kernel console with a kernel command line argument such as <varname>console=</varname> to | |
42 | get both kernel messages and a getty prompt on a serial TTY. See <ulink | |
