controller? in which context? xml-rpc will not be a bottle neck. There are very few commands being passed back and forth between the Lisp core and the platform port. Basically only on keypresses, or if the Lisp core itself initiates it. With regard to changing root, I have no idea what it means myself either, as I am not a Linux user, but from what I understand, it is necessary to get any Guix pack to work, I don't think it is a huge security risk. Then again, I am also not a Linux user, so hopefully someone more knowledgeable than me will chime in. Thanks for the well wishes!
