New File Mask

I am testing out FMS3 (from FMS2) for linux, and while I'm enjoying some of the new features I'm running into a problem I can't track down... For my FMS2 setup in conf/Server.xml I set the Mask node to 022 so FMS created new files under those permissions, that worked great. But I can't get the FMS3 install to recognize anything I set for the mask, so the new files are ALWAYS defaulting to 077, regardless of what's in conf/Server.xml (and from the documentation, it looks like the default is supposed to be 017 anyway).

Any ideas? Thanks!
