I have created an installation of OS X on a small drive. Everything has worked fine apart from the fact that it has used up most of my space. According the file size on each of the folders in the root directory do not amount to the space shown in the disk utility.
I have only done an install of OS X and DeployStudio so it surely should not be using up an entire 32 GB drive.
I have tried verifying and repairing the disk as well as a couple of reboots.
