The precedence for flag value sources is as follows (highest to lowest):
- Command line flag value from user
- Environment variable (if specified)
- Configuration file (if specified)
- Default defined on the flag
An issue arises in point 2, in the sense that configuration file refers to a single file containing the value for the env variable.
