I installed Debian 1.1 and found that my tex files were no longer leaving a margin at the top of the page. I traced it to /usr/lib/texmf/dvips/config.ps where a4size was set instead of letter. I don't recall any questions from the installation of the dvipsk about the paper size.
I don't know whether this is a common problem or something weird that I did but I thought I would just drop a note to the net in case anyone else is having the same problem. Nathan Salwen
