Hello, I'm building a computer cluster with about 20 nodes, all of them running ArchLinux. One of them is the 'login' node connected to the Internet, other nodes share Internet connection via the login node being a router. https://wiki.archlinux.org/index.php/Internet_Share Now, when I update the system (pacman -Syu) or install package on all node, I think it's a bad idea because it will consume the mirror bandwidth proportional to the number of the nodes. Maybe it's not a big issue for 20 nodes, but I'd like to learn nevertheless for future use, that: Is there a way to cache the pacman transaction at the login node, so that the communication between the login node and the mirror is constant, and the rest of communications only take place within the LAN? Is seting up a pacman mirror at the login node is the correct solution? Best, Takayuki Muranushi
