If you followed the discussion on devel-list last year, you'll remember that some of the savings were much more than 10 seconds (like cutting a 1:47 minute bootup in half). But even so, it's a usability thing -- when it comes to response times, a single second can make a difference. I think in this case it's about preventing the users from performing other tasks while waiting for the system to boot up. > Unless you need instanton technology (think Fedora Media Center) there > is no urgent need to speed up boot process, or not? > > I don't disagree with lowering boot time, but it isn't high priority. Well, since most of the investigation was already done in this area, it doesn't seem like a big investment. David Zeuthen[1] outlined the changes that need to be done -- start GDM early, improve the readahead list, cache kmodule, etc. Also, applying the techniques for improving the boot process can improve the responsiveness of the desktop in general -- e.g. by making better use of readahead, the startup times of Firefox, OpenOffice or Evolution could be greatly improved. Last, while not always a good argument, others have put lots of effort into reducing boot times. Ubuntu and Gentoo list it as one of the goals for their next release. Apple and Microsoft had done this long ago. [1] http://www.redhat.com/archives/fedora-devel-list/2004-November/msg01374.html -- Ziga
