I also found the insserv documentation frustrating when I first tried squeeze about a year ago. It took me a few tries to figure out the correct way of using overrides... When I was googling insserv last year, I landed on a d-devel thread where some posters were arguing that the current init system ought to be kept as an option for those who didn't want to use dependency-based boot. But the decision to make dependency-based boot inescapable seems to have been taken and, like grub2, we're stuck with it - until, it seems, squeeze+1/squeeze+2, when we'll have the immense pleasure of changing yet again to upstart or systemd. (By the way, Ubuntu laptops use upstart to allow script kiddies to boot faster, not insserv.) -- To UNSUBSCRIBE, email to debian-user-requ...@lists.debian.org with a subject of "unsubscribe".
