can’t boot with “/script/server” but works with “mongrel\_rails start”.  
why?

```

It looks like ./script/server cannot require ‘mongrel’ and it’s falling  
back to webrick.

To be more precise, script/server do wonky things with Mongrel:

It partially inializes Rails, then bootup the Mongrel code and then  
continue loading rails…

That’s not a nice thing to do 😛

I’ll suggest stay away from it… or create some alias for  
mongrel\_rails command 😉  
(mine is just ‘mongrel’)
