Re: I've forgotten...
"SysV scripts can be a little intimidating at first; you'll notice that the systemd-proponents seem to like to make a fuss about how many lines they are. But that length is a strength, IMO, not a weakness; you have the operation of the script laid out explicitly for your examination, rather than hidden within an executable. SysV scripts are very debuggable, and trivially modified if you want *your* box to do something different to what the package maintainer wanted."
That's also its weakness because it makes them delicate, allowing them to fail in obscure ways that results in a cascade where the reported point of failure isn't really the point where it started to go wrong.
Plus SysV doesn't use dependency triggering but delays. Not good if you need a quick turnaround like for a container.
