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.
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'.

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.
