Whenever I hear this complaint the first thing I think about is this Douglas Adams quote:
The major difference between a thing that might go wrong
and a thing that cannot possibly go wrong is that when a
thing that cannot possibly go wrong goes wrong it usually
turns out to be impossible to get at or repair.
Personally when doing operations related stuff I like to assume that everything will eventually break - though, hopefully not all at once.
That quote is entirely inapplicable though. It is in fact much easier to fix the simple, do one thing and do it well unix style applications. They are not hard to get at or repair. This is one area where I think the linux philosophy winning out over the unix philosophy has really cost us a lot.
