So you use the i586 optimizations on an i586, and the i386 > optimizations on an i386. Why is this so confusing? *shrug* Beats me. It's a problem with distributing binaries definitely, but since I gather the original poster just wanted to automate pbuilder and so on, my guess is a lot of people didn't bother to actually read what he wanted to do and just jumped on him assuming he wanted Debian to provide binaries. Alternately, I have a theory that the number of flames on d-d is constant over any given 8 hour interval, and so with a huge thread finally dying down, this one (and the WineX one) had to pick up. :P -- - Joe Wreschnig <piman@sacredchao.net> - http://www.sacredchao.net "What I did was justified because I had a policy of my own...
