13 systemd-getty-generator is a generator that automatically instantiates
14 serial-getty@.service on the kernel console(s), if they can function as
15 ttys and are not provided by the virtual console subsystem. It will
16 also instantiate serial-getty@.service instances for virtualizer
17 consoles, if execution in a virtualized environment is detected. If
18 execution in a container environment is detected, it will instead
19 enable console-getty.service for /dev/console, and
20 container-getty@.service instances for additional container pseudo TTYs
21 as requested by the container manager (see Container Interface[1]).
22 This should ensure that the user is shown a login prompt at the right
23 place, regardless of which environment the system is started in. For
24 example, it is sufficient to redirect the kernel console with a kernel
25 command line argument such as console= to get both kernel messages and
26 a getty prompt on a serial TTY. See kernel-parameters.txt[2] for more
27 information on the console= kernel parameter.

29 systemd-getty-generator implements systemd.generator(7).
