I’ll see if I can borrow one of our school’s raspberry pi, and see if I can sort this out.
That said, all I’d be testing is the installer and the services to get started, but I would not recommend using it to actually image systems. This is just my thoughts. The Pi is not a very powerful system. While I’m sure it will do what you want, it wouldn’t necessarily be the “best” method to do a “mobile” solution either.
