Yes, it has been replaced with a more complex setup. The new way is more efficient, safer and "cleaner", even though it's more complex to setup.

If you want to run two separate scripts you need two separate services. But it would be easier to have just one script (= one service) and give the 75 or 90 as parameter to it.
