I wanted to increase my boot time
[Karmic] Boot time has a huge regression (~1.5 min against ~40 sec for Jaunty)
performs poorly on slow HDD
I applied Scott J's method.

Please try the following:
sudo add-apt-repository ppa:ubuntu-boot/ppa
sudo apt-get update
sudo apt-get dist-upgrade
This should install an updated kernel package, and replace sreadahead with ureadahead.
The first reboot will reprofile your system, the second reboot should be substantially faster.
Please let me know how you get in (before/after bootcharts always appreciated)
Now I can't tell if I'm actually booting that new modified kernel version with -ureadahead, because I've been toying with GRUB 2. Also, now the fix for the GRUB 2 hidden menu doesn't seem to be behaving quite the same...
