Yesterday I had to install SQL Server 2008 for the first time. I went through it on a development server first before installing on a production server. As I went through the setup process I noticed one thing that I think is long overdue. The Database Configuration step is a great addition to the install process. It is about time that MS allowed us to seperate out where all the Database and Log files will be before we actually do the install. This makes it easy to break out tempdb from the other databases and also to separate your data and log files. Make sure that you take advantage of this and plan out where you want all of the data files and log files to be on the file system. This will save some headache in the future when you have to move all of your databases as well as the system databases.
