@command{sleeping-getty} waits until a selected
virtual terminal is brought to the foreground.
Then, or if the process started with this
virtual terminal in the foreground, the process
changes image to a getty program.

This is used to save CPU cycles during boot
to get a smoother boot, which is important if
your getty program does a lot of things, or if
your computer is not too powerful. It also
reduces the memory footprint.
