This should never happen on a Mac: “reboot in single user and type several cryptic commands if you can’t log in after upgrading to Leopard”. It will give months of ammunition to the paid Ubuntu shills, and even let some Windows users feel good about themselves (“see! see! I told you the grass wasn’t green over there!”).

Changing how user passwords are stored: good. Forgetting that they used to be stored another way in a previous release: bad.

As usual, when my copy arrives, I’ll install onto a test machine and let it bake for a few weeks. My primary machine won’t get upgraded until we finish moving the company into a new building and I get back from my upcoming vacation in Japan.
