f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering <para><filename>systemd-getty-generator</filename> is
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering a generator that automatically instantiates
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering <filename>serial-getty@.service</filename> on the
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering kernel console <filename>/dev/console</filename> if
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering that is not directed to the virtual console
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering subsystem. It will also instantiate
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering <filename>serial-getty@.service</filename> instances
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering for virtualizer consoles, if execution in a
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering virtualized environment is detected. This should
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering ensure that the user is shown a login prompt at the
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering right place, regardless in which environment the
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering system is started. For example, it is sufficient to
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering redirect the kernel console with a kernel command line
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering argument such as <varname>console=</varname> to get
f220d83cbc63678c765dd0b80983f17b1d5e615bLennart Poettering both kernel messages and a getty prompt on a serial
