What is hard to understand is if I take the same EXACT
kernel Centos take, which I assume is available, and I
compile everything Centos compiles in, except I
compile some hardware in the kernel rather than
modularize it (as Centos does), how exactly is that
going to break functionality?  How exactly is removing
ext2 (if it is included in Centos default compilation)
from the kernel is going to break Centos if I don't
ever use ext2?

ps...  At this point in the discussion it is not about
how to compile or why/why-not compile the kernel
anymore.  The how question is going to be solved.  If
you don't want to have a rational conversation about a
feature of any source-base package you don't have to
scream, all you have to say "It is the way it is,
because Centos says so, and if you don't like it,
don't use it."

If this is/was the wrong place to have this
conversation, my apologies.
