Well, compiling your own kernel is the basic way to get new drivers into
your system. There's also a lot of functionality that is kernel-based,
like the firewall. That's the reason you see this crop up so much.
There's a lot in there. If you need something enabled for something
you're working on, you'll have to recompile, but I hesitate to say it
"fixes" anything.

Nope. If you're running as root, then all your child processes will
also run as root. So, if you're running as root in a terminal window
and invoke top, top will be running as root, but the window itself will
be running as the normal user, since the normal user is what started
that program.
