Don’t minimize those strengths. Init.d scripts are something you can figure out just knowing a bit of shell script, or historical knowledge from before there was an internet. For something I rarely use, why do I need to learn something more complex to do the same thing - I either haven’t been sold on all the new functionality they piled in or do not need it. After all these years crowing about the Unix/linux way being many independent flexible tools that can work together, why do we now have this all-in-one monstrosity that might as well have come directly from Microsoft?
