By modifying the boot-time readahead to be at lower I/O and processor
priority than the boot scripts and asynchronous, I see a 20% reduction
in overall boot time (from installing bootchart) on my desktop: 41s
down to 33s.

I've produced a complete and tested debdiff at:

and prebuilt a jaunty/intrepid x86-64 package (sorry, no ia32 h/w) at:

I'm interested in feedback and what performance benefit others see, to
see if it's worthwhile we get this reviewed and uploaded.

Happy booting!
