sources.list - Way to determine US or UK
I have created a custom debian netinst USB stick. It has the default UK repositories in the sources list, but people in the US also need to use the stick from time-to-time.
Would it be a bad idea to mix US and UK repositories in the sources.list? Would Debian be clever enough to pick up the best repo depending on where the user is using the OS from? Or would I need to be a bit clever and create some sort of script to deal with this. (I am avoiding non-free/experimental software).
