I don't think this argument holds for lightly used parts of the mirror. And if the disk breaks, too bad, just download the lost bits again. I find it hard to believe you would need an enterprise class storage system to store a lightly used mirror. Even with raid 1 it would still be under 200 euro. > Second, I have yet to see the first mirror that mirrors Debian > exclusively.

The 98% criterium doesn't make any sense as it might not make sense to have some packages on some architectures. Happy Hacking, p2.
