systemd-getty-generator — Generator for enabling getty instances on the console
/usr/lib/systemd/system-generators/systemd-getty-generator
systemd-getty-generator is
a generator that automatically instantiates
serial-getty@.service on the
kernel console /dev/console if
that is not directed to the virtual console
subsystem. It will also instantiate
serial-getty@.service instances
for virtualizer consoles, if execution in a
virtualized environment is detected. Finally, it will
instantiate
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 the generator
specification.
