description   "Record that system boot is complete"
author        "chromium-os-dev@chromium.org"

# Completion of this job is the key to starting the 'system-services'
# job.  The job is also the official timestamp for boot time
# measurement.  This job needs to run separately before
# 'system-services' because the amount of work that starts with
# 'system-services' could otherwise delay the 'bootstat' timestamp,
# and make boot time measurements less reliable.

# Note, the 'start on' line is modified by chromeos-factoryinstall ebuild
# and factorytest-init ebuild. Please do not change it without also
# changing those references.
# TODO(jrbarnette) The external dependencies that edit this line should
# be eliminated.
