For my OLPC/XO-1 laptop these days, I'm using the Sugar-on-a-Stick kickstart files[1]. I want my XO to boot fast, not because I boot it a lot, but because it boots really, really slowly right now. So I installed bootchart, changed olpc.fth to use it, rebooted, and voila, got this chart:
http://www.martindengler.com/proj/soas/Soas-200903022241-bootchart.png Then I edited /etc/bootchartd.conf to use process accounting, and got this chart: http://www.martindengler.com/proj/soas/Soas-200903022241-bootchart-psacct.png I booted without my SD card (which isn't the boot device - I'm booting off NAND) inserted, and got this chart: http://www.martindengler.com/proj/soas/Soas-200903022241-bootchart-psacct-nosdcard.png So there's some work to do to fix some SD card badness... Meanwhile, looks like I should get more familiar with rc.sysinit. The data for the above charts are all available at: http://www.martindengler.com/proj/soas I figured some people might be interested in this. Thanks to sdziallas, erikos, marcopg, and the whole SoaS team for their great work.
