Okay.. Okay.. don't flame. but you may find this to be useful.
In Gentoo, there's a bugzilla on getting boot-up to be faster. One way
in which it is done (not new news) is to do parallelisation.
In my experimenations (look at Bootchart) on this that I've moved from
1:07 to 0.49 sec of boot-up by shaving off a few items and what nots.
one interesting thing which didn't actually made boot-up faster but what
it did was to present the X/GDM screen to the user and runs the other
startups iin the background. Its an interesting and good concept for the
desktop, but still, since it actually _adds_ to overall boot up time, I
didn't want it.
