Criticisms of systemd say it does too much, so maybe every basic animal on the farm is systemd? Orwell is complaining about how the pig is overly complicated for a farm animal.
If I really break it down, I guess the author is saying that while it could be cool to have talking pigs, they have no place in a production farm. The average Linux admin doesn't want tools that can do everything, they just need the thing done??
Orwell, the user, is a supervisord pleb that already understands the limitations of sysinit but their inability to read some man pages results in them writing a long-ass book instead.
I was referencing the lengthy screeds against systemd that appear on the internet - those do not strike me as being productive for learning systemd - they appear to me to be justifications against trying to learn the thing. Is this the style of writing that has helped you or were you unaware of what I was referencing?
