Why does this not supprise me?

For you it is clear what 'broken means'. I have the same problem
talking secure identities inside my company. It is clear to me, but
others just miss the important points. And you get frustrated going
back to 'basic principles' and teaching them again....
So thanks for putting up with me, who rarely has to dig into these parts
of systems.

Ah, perhaps my dyslexia, but I was wondering what drivers or other
things I might have to contend with. If it is 'just' kernel* I can deal
with that.

Again, a bit of 'magic' here that 'yum upgrade' knows what should be
present and sees to it that these packages get installed. Again,
thinking that more than kernel* would need to be removed, then how would
it get reinstalled?
So off I go try again. The box had been off for a year; it was a DNSSEC
tester (I need to replace my router(s), I think to get DNSSEC working
right, and that project is on hold). So it was quite back-leveled. If
I end up needing to do a reinstall because I stumbled, so be it as a
learning lesson.
