I’ve heard BSD people criticize Linux ecosystem as “fractured”, and this discourages me from BSD. I see Linux ecosystem as one that grants you choice, and I love that. This criticism gives me the impression that BSD takes that away, that where will be one standard way to do many things. Maybe I am wrong or misunderstood.
What’s the benefit? You listed some minor things like ZFS and systemd, but is there a major benefit?
Also, can’t you do that with Linux? I use openRC on gentoo.
