I was recently given the task to remove Windows XP from some 15 computers in a primary school, install Lubuntu 12.10 on them (all too old for Gnome/Unity) and set up Scratch so the students can start learning coding in a month or two.
The problem is: although I've been using Linux for a decade now, I've no idea of how to set up a "master" computer to deal with the updates and maybe even broadcast whatever is happening on its screen to all the "slave" computers in the lab.
The only useful answer I found here was this one regarding the use of "squid-deb-proxy" to deal with the updates in an efficient way.
Any how tos, tutorials or tips from someone who's done something similar?
Much appreciated. Thank you.
