is this the right format:
http://mirror/debian/security squeeze/updates main contrib non-free
http://mirror/debian/security squeeze-updates main contrib non-free
squeeze/updates VS squeeze-updates (slash vs hypen).
I have seen both and the new debian sequeeze 188.8.131.52 seems to have the hypen version? Is this the new format? (Maybe I am wrong, it seems the current debian also has both, so they seem to be something different, who can explain it what the difference is.)
