hhvm.server.startup_document does not seem to do anything

HHVM Version

HipHop VM 3.17.0 (rel)
Compiler: tags/HHVM-3.17.0-0-ga34af693b558ed98ffafc3f5127e00959e145e4f
Repo schema: 8eda451fe80742a18e0e2e8917aa4053c2c1afe7

Standalone code, or other way to reproduce the problem

/home/user/startup.hh

<?hh
file_put_contents('/tmp/startup.txt', 'contents');

start server

hhvm -m server -p 8080 -d hhvm.server.startup_document=/home/user/startup.hh

Expected result

/tmp/startup.txt is created

Actual result

/tmp/startup.txt is not created

Looking at hphp/runtime/server/http-server.cpp, there is no reference to StartupDocument option at all

This was deleted in august. If you want to check if HHVM is running (what you appear to be doing with your startup.txt) look for the pid file in /var/run/hhvm/. If you are trying to warmup HHVM (what this used to be intended for) see the new way of doing this here.
