hi peter --

bootanim does both the boot-time animation and the shutdown
ul-warning screen.  it does the boot animation in an extremely
efficient manner, shaving 10 or 11 seconds off our current boot
times:

    http://lists.laptop.org/pipermail/devel/2009-March/023688.html

given the optimization that bobby and mitch put in, i suspect
plymouth won't match it, time-wise.  (though i'd love to be proven
wrong, of course!)
