Hi all, The new kernel 2.6.30-1-686 came into Debian this last week and I got the itches to do some fast boot testing. The result is still disappointing for me, its still the same as a year back and the kernel even got slower compared to 2.6.29-2-486 but there are some good points.
The parallel booting of script kind of works now. I added my results to the wiki I hope that's ok: http://wiki.debian.org/BootProcessSpeedup#Testsresultsofusers purpose: I build a lot of different linux systems, some just need fast bootup like multimedia devices, easy internet devices, netbooks et cetera. one of the requirements is maintainability and stability. I don't get maintainability by recompiling my own software, so that is not an option. What is an option is to tweak all the configuration systems I can find, test them for stability and use them. major issues: the udev process takes an awful lot of time it just stays for more then 7 seconds in the "Waiting for /dev to be fully populated" state probably caused by udevadm settle. We need to tune udev to become way faster and keep the solution easy to use and maintainable. I use grub2 and it has no behavior like hiddenmenu, you can see three flashes during boot before it comes to the steady "loading system" state. sometimes my asus eeepc 901 just won't turn off at the last stages of halt. I got the feeling that some hardware (audio, network) is not correctly deinitialized and makes the shutdown process hang. SySRq doesn't react in this stage anymore so the kernel is probably down already. result: my boot process is around 13 seconds and 7 á 8 of them are caused by udev. I hope somebody will pick this up and also improves there systems and hopefully find some good way to speedup the hole udev stuff with good maintainable solutions.
