But note that this way you alter *all* queued jobs that way,
regardless if they are created with the assumptions of sysv behaviour
or if they were created in code that understands systemd's semantics,
and actually cares for the correct ordering..

I'd strongly recommend finding local solutions to the problems at hand
here, rather than changing behaviour for all other non-sysv code as
well...
