Giusto per capire la differenza fra init e il nuovo Upstart in Edgy:<\/p>\n
\nA dependency-based init daemon would start networking because it’s a dependency of the Apache goal, and would mount the filesystems because they are a dependency of both the Apache and gdm goals. If either gdm or Apache fail to start, this means that networking won’t be available unless it itself is a goal.<\/p>\n
An event-based init daemon works the other way around; it starts off with a single event such as “startup” and everything else will be run by that or subsequent events. An event-based init daemon has no need for goals or runlevels, the system will boot as far as it can get with the available hardware; for a distribution, this means that the default installation can be far more flexible.<\/p>\n
Networking will always be started if networking hardware is available, assuming the default configuration is for DHCP to be attempted. As with the dependency-based system, if no hardware is connected at boot time, Apache still won’t start. However, with an event-based system, if the network card is plugged in a few minutes later, once it’s been retrieved from the back of the sofa, Apache would be started automatically.\n<\/p><\/blockquote>\n
