You could use a startup script in windows to check the available space and extend the partition by an amount if you wanted to.

Thanks, that seems to have fixed it.

Since Fog uses several servers and other components that use usernames and passwords, and since it seems that the installation script doesn’t set them all correctly, is there any documentation for Fog that explains how to set them all up correctly?

I reset the permissions of /images and everything under it to 777 (again), and also set the owner and group to root. This seems to have fixed the problem. Not sure why it didn’t work with the first couple of images I created, but it seems to be working now. Thanks for your help everyone 🙂
