That's a good idea.

In addition to that, I saw this project for Windows installs:

Depends if you want to re-install, or quickly boot an already installed

using the "net rpc shutdown" command.
So assuming you run Samba on your head node you could probably reboot
your master mode from Windows to Linux then issue this command.
