The dfs_config Environment Variables
Many variables specific to DFS are set explicitly in the dfs_config component script. You can use these variables to supply information to dfs_config instead of typing the information in response to prompts.
The following table shows the DFS values that are set in the dfs_config component script. In the table, the term default refers to the setting assigned to the environment variable by OSF.
