BTW, I installed the Jaunty kernel in Intrepid and it sped up my boot because it has more drivers built in so less probing and loading is done in the initrd. However I will encourage interested people to install Jaunty to a separate partition and help sorting out boot performance issues as it is being developed, it is a stated goal of Jaunty to get the boot time down, but more testing on different hardware will help.
will try that
how did u install jaunty kernel on intrepid??? i have a separate 9GB partition where i could install it... i will try it when i have some spare time...
and then click through the right package (for instance linux-image-2.6.28-5-generic) and find the .deb for your architecture. It will install along with the old one, so you can choose which kernel to boot in the grub menu.
This will void all warranties of course
For some hardware you might need an updated corresponding linux-firmware package as well, https://launchpad.net/ubuntu/+source/linux-firmware/
Note that I don't post more direct links, they will change with newer releases, and also, those who don't understand much of this should probably not try it.
since when does ubuntu come with warranty ? [maybe for preinstalled ubuntu dell systems!]
will be trying the newer kernel or also the alpha jaunty in the separate partition...
My ubuntu 8.04 boot 29s... with complete localhost server = lighttpd + php5-cgi + mysql5-server
My system takes roughly 40 seconds just reading the file list, which has about 3500 lines, is this normal?

I had used these tweaks a long time ago.
All had been fine until recently. After running a profile from the kernel line my machine randomly failed to get a DHCP address on boot.
Re-adding the --background switch to S01readahead fixed it completely.
This issue seems very timing specific.
If you start init.d/networking a few milliseconds later, as S60, it works fine.
Or you could run /etc/init.d/networking restart at a much later point, and again, it's fine.
So, if you have connectivity issues using anything but 'roaming mode' in Network Manager this is a possible reason for failure.
Something to keep in mind when you tweak your readahead.
