Frankly the odds are that Zach is deploying to a system that runs systemd or Upstart, both of which I would count as "modern" (this is about whether your init can supervise processes in a useful way).

For context, moving /var/run to /run was proposed early in the systemd days, and has since been incorporated into the FHS. It was also adopted by other distributions because, frankly, it's a good idea that solved real problems.
