Personally I haven’t. While Linux is imperfect, choosing the right distro makes the rest of the experience straightforward. And with it’s whole complexity, I find Linux more user friendly than Windows. Even driver issues, broken shadow file ownership and KDE specifics only made me more confident about my choice to use Linux after I solved everything.
I’m saying that complexity could easily be modularized inside SysV init, not requiring a restructuring of things like “logfiles are no longer files in /var/log”
That phrase has proven to be a source of endless headaches any time someone in charge is stupid enough to believe the person that tries to sell them that.
