Plymouth is a bootsplash for Linux. It supports animations. It makes use of Direct Rendering Manager (DRM) and kernel-based mode-setting (KMS). It gets packed into the initrd.
Besides eye-candy, Plymouth also handles user interaction during boot.
It was first included in Fedora 10 "Cambridge" shipped on November 25, 2008 where it replaced Red Hat Graphical Boot (RHGB). Ubuntu includes it in the 10.04 LTS "Lucid Lynx" release shipped on April 29, 2010. Mandriva switched from splashy to Plymouth with version Adélie (2010.0).
