Looking at my 'I only do one thing' Pi running 94 different processes, realistically how many of them do I need? And how could I get rid of them?
I want to examine the pi as a reasonably real-time signal processing unit.
I don't need disk access except to load the code. I may not need network access. I don't need logging. I sure don't need systemd. I don't need a gui.
I just want to run one high priority daemon and one lower priority demon, with shared memory between them...is there something simpler than Linux? More like e.g. DOS?
