We have a need to have production work machines (tin, terbium) to have HHVM (and thus Trusty). Use case is maintenance scripts that depend on HHVM.
sudo -u www-data hhvm -m debug /var/www/w/MWScript.php extensions/Flow/maintenance/foo.php --wiki=somewiki
NOTE: This also needs to be mirrored into Beta (somewhere, currently we use deployment-bastion like tin, maybe making a terbium-like in Beta?).
[ ] create Trusty instance to replace deployment-bastion
[ ] migrate to the new instance (Jenkins, scripts, whatever is hardcoded).
[ ] provide Trusty replacement for tin
[ ] provide Trusty replacement for terbium
[ ] migrate prod
[ ] update deployment / work doc
