Etcnet was very involved with scripts which was always a problem for
Red Hat. Many Red Hat scripts have been known for being substandard in

However, any daemon can work well if proper scripting is applied and
mistakes are corrected properly.
Scripts are just the easiest thing to blame since everyone can see them
and far more users are capable of reading (and thus critiquing) them.
Scripts are no more different than any other piece of code that makes up
a system, but they are a lot easier to modify and understand (and thus
critique -- wait, I already did that one) to suit to your individual
purpose. That is why scripts have been strewn across *NIX since the
dawn of time. (Or the Epoch. Close enough. That's the one that
matters, anyway.)
Scripts are a fundamental building block across many aspects of *NIX, so
to focus on just init is a bit tunnel-visioned.
If a script is bad, send a patch. And getting rid of scripts altogether
won't fix any problems of quality or reliability; it will just put any
badness in the binaries where you can't easily
understand/modify(/critique!) any issues that an init system
who-will-remain-nameless might (read: will and has) caused.
I for one like scripts: start, stop, _etc_. Same scripts work for
SysVinit or BusyBox or conceptually any arbitrary init system that will
have them. I mean, the convention is part of the Linux Standard Base,
fer cryin' out loud!

Using some strange new non-script init file format is typically what
sours me on many of the alternative init systems. Pretty much every
service already has an initscript for itself available, and if not, they
are very easy to make. You'd think someone would focus on
fixing/streamlining/refactoring the oft-called crufty init executable
instead of struggling with an file format when one already exists and is
widely available for use. Simple, yes, but when has KISS been a bad
thing before?
