+Special note on the tmpdir java_arg. The puppet-server installation requires a tmp dir with a mode of 1777 and a tmp folder which is NOT mounted with the noexec parameter.
+Otherwise the installation will fail with this strange error message:
+```
+Caused by: org.jruby.embed.EvalFailedException: (Error) Cannot determine basic system flavour
+```
