An Upstart job for a database service fails to start on boot, but starts successfully when manually run with 'initctl start mydb'. The job definition includes 'start on started networking'. What is the most likely cause?

The networking job is not emitting the 'started' event.

The database job is not in the correct directory.

The networking job emits its 'started' event before the database job is loaded.

The database job has a syntax error in its script section.

An Upstart-based system has a custom job that must start a service only after the filesystem /var is mounted and the network interface eth0 is configured. The job currently fails to start reliably. Which Upstart stanza should be added to the job definition?

start on (filesystem and net-device-up IFACE=eth0)

start on filesystem or net-device-up IFACE=eth0
