I'll be working from a facility with restricted internet access. Where does
pacman source its downloads from? Is it from https://sources.archlinux.org/sources/packages/?
Also, correct me if I'm wrong, but
pacaur sources its files from whatever repository is listed as the upstream URL, right? Often that's GitHub.
edit: Also, I imagine that the Arch package repository has mirrors. It seems the one I posted is served from Germany. I'm not exactly sure what Internet restrictions I'll be facing, but I imagine I could select a mirror if country-of-origin is a problem.
