It pretty certainly is an issue in start-stop-daemon which can be
avoided by not using --name.

This should either be assigned to sysvinit-utils (which provides
init-d-script), to dpkg (which provides start-stop-daemon) or back to
opendnssec to not use init-d-script and --name.

Read the man page of start-stop-daemon:

Not a bug invoke-rc.d and thus init-system-helpers.

The original bug reporter was using sysvinit. I'm pretty sure it doesn't
happen under systemd, as you provide a native service file.
