upstart program

because the rc-sysinit start on condition is as follows: Start on filesystem and net-device-up Iface=lo Task Rc-sysinit calls Telinit. The Telinit task emits a runlevel event that triggers execution/etc/init/rc.conf. Rc.conf executes all the scripts under the/etc/rc$.d/directory, and Sysvinit is very similar, and the reader can refer to the first part of this article for a description. Things to note when developing a program As a

the work is done, the Mountall task issues the following event: Local-filesystem,virtual-filesystem,all-swaps,Where the Virtual-filesystem event triggers the Udev task to start working. Task Udev triggers the work of Upstart-udev-bridge. The Upstart-udev-bridge will issue a net-device-up Iface=lo event, indicating that the local loopback IP network is ready. At the same time, the task Mountall continues to

Brief introduction Recently do Linux course design (kernel cropping and file system customization), selected ubuntu10.10 as the platform for the experiment. Different Linux distributions, the user state initialization mechanism is different, Ubuntu since the 6.10 version of the use of newer upstart mechanism for system initialization. Upstart is an event-driven service startup mechanism that enables multipl

a particular program when something changes in the system. Most of the programs that are running here are scripts to start or stop the service. This configuration is actually very similar to the notion that System V runs a link to the init script at a certain runlevel. Just upstart more flexible, upstart can not only start or stop the service when the RunLevel c

For a long time, most Linux distributions have been using the init system introduced by UNIX System V. Init is generated by the kernel itself. The task is to start the remaining part of the system, generate and monitor all other processes, and check whether it is stopped or frozen. Although System V init has been running well in the past, it is a little late. This is why Ubuntu 6.10 (edgy EFT) uses upstart to replace the aging init system. The goal
