The RPMs use a separate "startup.log" (I think that's what it's called
- or at least something similar). While not ideal, I think that's a
fairly reasonable workaround for that issue. Startup issues aren't
that common - and it's not unreasonable to look in "startup.log" if
things don't start, I think...
