Yes, I have to admit finding the idea that unloading an unused module
causes trouble a bit amusing ;) I've done it plenty of times, and the
only time modules have caused me trouble is when I loaded something,
especially when using --force.

I would not consider building a monolithic kernel. Modules are just
far too convenient. Imagine your network card dies, and the spare you
have has a different chip - you'll be cursing for the rest of the day.
Many problems can be fixed by reloading modules, including security
upgrades.

It was considered more secure to have no modules, until someone figured
out how to load modules anyway (or something like that).

What real advantages does a monolithic kernel have?
