upstart-events - Well-known Upstart events summary
Event Summary
This manual page summarises well-known events generated by Upstart running both as the init(8) daemon
(process ID 1) and a Session Init (process that supervises a user session).
It is not an exhaustive list of all possible events, but rather details a standard set of events expected
to be generated on any Ubuntu system running Upstart.
The primary tables, Table 1 and Table 2, encode the well-known system and session events respectively,
along with the type of each event (listed in Table 3), the emitter of the event (see Table 4) and the
approximate time at which the event could be generated. Additionally, the Note column indexes into Table
5 for further details on a particular event.
See init(8) for a table summarising job goals and possible state transitions.
Note that some events listed in Table 1 may be available to session jobs (depending on when the Session
Init starts). Those events that are available will be prefixed with :sys:. See upstart-event-bridge(8)
for further details.
The Ref (Reference) column is used to refer to individual events succinctly in the Time column.
Note that the '<' and '>' characters in the Time column denote that the event in the Event column occurs
respectively before or after the event specified in the Time column (for example, the mounting(7) event
occurs "at some time" after the startup(7) event, and the virtual-filesystems(7) event occurs after the
last mounted(7) event relating to a virtual filesystem has been emitted).
For further details on events, consult the manual pages and the system job configuration files, usually
located in /etc/init.
