Some examples of Upstart events generated by this bridge:

Event emitted when a network device is added.


Event emitted when a network device is removed.


Event emitted when a graphics device is available to the system.


upstart-udev-bridge receives information about kernel uevents that udev(8) has completed and creates init(8) events for them.

It emits events which match the pattern "S-device-A" where 'S' is the udev subsystem and 'A' is one of added, changed or removed, which correspond to the past tense of the udev 'action'.

See udev(7) and for further details.

Assuming /sys is mounted, possible values for subsystem for your system are viewable via /sys/class/.



Detach and run in the background.


Enable debugging output.


Show brief usage summary.


Do not modify udev message contents. By default, all udev data will have non-printable bytes removed. This option reverts the behaviour to not modifying the data in any way. This option is not recommended since specifying it could result in udev(7) events not being emitted as Upstart events should any of your hardware expose non-printable characters to the kernel. You can establish whether this is happening by running without specifying this option but with the --debug option.


Enable verbose output.
