Public bug reported:
The systemd generator for openvpn (filesystem: /lib/systemd/system-
generators/openvpn-generator; git: openvpn/debian/openvpn-generator)
does not seem to work correctly with multiple configurations.
When run a second time the symlinks exist and the generator fails on the
first config and does not make it through the loop of all configs. This
means if a config is added later and glob sorts after the first config
it will never be linked. I believe the ln -s invocation should be ln
-sf
