If you mean the kernel, you probably should have said so, especially
since this thread is about login authorization, not the kernel.  I
wasn't talking about "add-on" SRPMs; I was talking about the SRPMs Red
Hat ships, which are just as easy to use as "add-on" SRPMs.

And if we are talking about the kernel, then yes, I have built a Linux
kernel from scratch.  Have you ever tried to build a NetBSD kernel
from scratch?  Can you honestly say that either requires more
"specialized knowledge" than the other?  Both builds are weird and
confusing to a person who has no prior knowledge of the underlying
hardware platform.
