I bought a NAS to store my media files and I'd like to automount the volumes on startup. Currently I'm opening those volumes as a Login Item under System Preferences > Accounts.

This works, but it unfortunately also pops up each volume in a new Finder window on boot up. Checking the hide on the items only hides the processes, not the resulting Finder window from those processes. A solution that avoids those Finder popups would be great.

I'd like to avoid any 3rd party apps to accomplish this too.
