I believe so, but I'm not fully sure. But usplash in ubuntu is significantly ahead of the debian version and I expect that they have put some work into it, as a faster boot is also an ubuntu goal. > Are you (and/or whoever maintains the splash packages) aware that sysvrc in > the makefile concurrency mode (which should become the default at some > point in the future) does not handle the splash progress bar API?

Yeah, I dont think the progress bar is the most important thing usplash gives. Getting rid of/hiding the "confusing kernel messages scrolling by" (*) is what I consider the most important thing. But then, if the boot time is 60 secs, some people might prefer a progress bar still, or maybe not a progress bar but any progress indicator of some sort. So my idea is definitly to provide different kinds of themes, for different use cases. (*) oh, yes, sometimes those "weird" messages are absolutly must have (and for some percentage they are of course not weird at all :) But even I, who understand them, usually just prefer my system to boot up quiet and shiny. > What are the plans for squeeze?

Cool! Very. regards, Holger
