A lot of people seem to have problems with this auto-install thing. I've done 3 installs (1xWP1.02 and 2xWP1.2beta) now and had to create wp-config.php by hand each time. Not a big issue but if I'd known the auto-install wouldn't work I wouldn't have tried to figure it out and could really have done it all in 5mins.
Actually, looking at http://wordpress.org/docs/installation/5-minute/ now it does say you need to create the file yourself.
But on the other hand, looking at the readme.html in 1.2 beta, it suggests that it can also be created automatically by running wp-admin/install-config.php
So what's correct? Is it server dependent or something? And can anyone report a successful auto-install? If not, why not just change the readme until it actually works? I'm sure this would be spare WP newcomers some trouble.
