description "Job to trigger standard system services"
author "chromium-os-dev@chromium.org"
# This job is used as a milestone marker for jobs that want to start
# once at system boot, but don't want to delay bringing up the login
# screen. Jobs depending on this job should provide a service that
# is not needed at login and not specific to a user session, but
# that should start once at boot time, possibly staying up for the
# life of the system.
#
# Standard usage:
# start on started system-services
# stop on stopping system-services
# Jobs that normally terminate in a bounded time (i.e. don't use
# 'respawn') should omit the 'stop on' stanza.
#
# Jobs that depend on system-services as described above can assume
# that all services implied by 'boot-services' are available. Jobs
# must not make assumptions about whether a user is logged in.
#
# Jobs that depend on system-services may fail to come up if Chrome
# fails during boot; see the 'failsafe' job for an alternative to
# this behavior.
start on started boot-complete and started boot-services
stop on stopping boot-services
# We only want to start once, but 'stopped boot-complete' happens
# every time Chrome displays the login screen. To avoid firing
# every time, we omit the main process: upstart marks us running
# on the first event, and ignores all subsequent events until we
# stop.
