The Install Tree Location
You can install the DCE binaries from an install tree stored on your file system or from an install tree stored on a media device. If you install from a media device, dce_config must copy each file it needs from the device as it needs it. Because it is faster to install from the file system, we recommend that you use the tar command to copy the install tree to a directory named /opt/dce in your file system.
If you are installing from an install tree stored on the file system, ensure you have access to the tree either on the local machine or through a remote mount.
During the installation, you will be prompted to specify the location of the install tree. If it is on the file system, you supply its pathname. If it is on a media device, you supply the device name.
