passed this way, i.e. look for `$CREDENTIALS_DIRECTORY` and load the credential
data it needs from there. For daemons that do not support this but allow
passing credentials via a path supplied over the command line use
`${CREDENTIAL_PATH}` in the `ExecStart=` command line to reference the
`${CREDENTIALS_DIRECTORY}` in the `ExecStart=` command line to reference the
credentials directory. For daemons that allow passing credentials via a path
supplied as environment variable, use the `%d` specifier in the `Environment=`
setting to build valid paths to specific credentials.
