startup
startup(7) Miscellaneous Information Manual startup(7)
NAME
startup - event signalling system startup
SYNOPSIS
startup [ENV]...
DESCRIPTION
The startup event is generated by the Upstart init(8) daemon after it has completed its own initialisation and is the signal that the rest
of the system may be started.
Typically this will involve checking and mounting the partitions and drives that form the filesystem, loading drivers for connected devices
and starting the X windowing system or other login environment.
In the default Upstart configuration, the primary task run on the startup event is the /etc/init/rc-sysinit.conf job responsible for gener-
ating the System V compatible runlevel(7) event. See that page for a more detailed explanation of this process.
Paradoxically there is currently no corresponding Upstart-native event signifying that the system is to be shutdown, only the System V com-
patible runlevel 0 and runlevel 6 events provide this functionality.
EXAMPLE
A service with no other dependencies run on startup might use:
start on startup
