# TODO(beeps): The right way to create these status logs is by creating a job
# object and invoking job.record on it. However we perform this template
# hack instead for the following reasons:
# * The templates are a lot easier to understand at first glance, which
# is really what one wants from a testing interface built for a
# framework like autotest.
# * Creating the job is wedged into core autotest code, so it has
# unintended consequences like checking for hosts/labels etc.
# * We are guaranteed to create the bare minimum by hand specifying the file
# to write, and their contents. Job.record ends up checking and creating
# several non-essential directoris in the process or recording status.
