Most of these problems have been fixed as of the January Creators Update for Windows 10. SSH server is still iffy, because Windows 10 comes with an SSH server (not OpenSSH), which you'll have to disable. It was very weird to try to SSH into WSL and get a cmd.exe prompt. Also, once you install opensshd with apt, the server is only active while its terminal window is open (since closing the terminal window kills the WSL init process).
