Two week warning on this potentially breaking change. I plan to switch
the default from Precise to Trusty on or after 2016-10-17. If your
jobs (including cron jobs) will only run on Precise you need to add
`-l release=precise` to jsub commands or `--release=precise` to
webservice jobs.

Note that pinning your jobs to Precise is a temporary fix as all
support for Precise will be removed in March 2017. See
[[wikitech:Tools Precise deprecation]] for more information [0].
