plymouth - Plymouth graphical boot system.: "plymouth - graphical boot animation and logger
Plymouth is an application that runs very early in the boot process
(even before the root filesystem is mounted!) that provides a graphical
boot animation while the boot process happens in the background.
It is designed to work on systems with DRM modesetting drivers. The idea
is that early on in the boot process the native mode for the computer is
set, plymouth uses that mode, and that mode stays throughout the entire
boot process up to and after X starts. Ideally, the goal is to get rid
of all flicker during startup."
