I couldn't spend more time with that. But my overall experience with WSL is positive at least I don't need to install cygwin just to get basic tools. Windows fs is mounted on /mnt/c which is easy to type. I assume most of important syscalls are already implemented to translate. Even though sometimes bash.exe stops responding and maybe more enter key works. But bash is working like a jailed process, WSL does not report Windows processes that run to it. Which is a deal breaker. Frustrating maybe even more than running without dbus.
