Some users seem to be confused by the fact that our URLs in the manual don't work for them. This is most likely because they copy them without reading the rest of the text which clearly says they should replace @var{system} with one of the supported values. One example of this confusion is this conversation: https://mastodon.social/@Nixfreak/104224784493287104 Since our current approach doesn't seem to be very effective, I propose to change the URLs and file names with actual ones, using x86_64-linux as the system because this is the most popular platform that we support nowadays. I keep mentioning the other architectures as alternatives, hoping that users will notice the x86_64 in the URL and keep reading to learn how to install Guix for another architecture if they want to. Wdyt?
