It has the thing that systemd and journalctl are poor clones of.

Their ergonomics (especially the log viewer) are much worse than sysvinit/syslog, but they mostly work.

I say “mostly”, because, like systemd, sometimes force disabling a broken service silently fails, even after reboot.

Darwin uses launchd/libxpc. journalctl's job is handled by the `log` command, with appropriate predicate filters to winnow out the relevant stuff from the chaff.

No.
