What goes "in" a kernel?
A long time ago, I built a Gentoo installation. I managed to get through the install docs, which were pretty obtuse at the time, and booted into my new distro. Yay.
'cept for one thing: I didn't have network access.
Somehow, even though the installer requires network access, when I booted into my machine, I had no access.
I theorized that the problem was I didn't build in support for my network card into the kernel.
So, this question...
Is the above true? Should I have built into the kernel support for my NIC? Is this required? What does it mean to build a kernel anyway?
