Yes, and yes.

This isn't necessary, though I'm sure Debian users like the idea.  Red Hat
has admittedly become much more agressive in their upgrades.  They want
those requiring stability to purchase their Enterprise versions, while the
bleeding edge folk can stick with their "regular" distribution.

In other words, update to the latest Red Hat Errata for the kernel and
glibc.  Updating both of these fixed all the problems I was having.

I had some bad problems when upgrading glibc, even with the correct i686
packages.  I ended up having to go to the 'rescue' mode after booting from
the CD and doing an 'rpm -e --root=/mnt/sysimage [old glibc]' and
'rpm --root=/mnt/sysimage -Uvh [new package]' to get things working again.
A big pain since I do 99.99% of my work 15 miles from my servers, but it
wasn't that difficult and I've had no problems since.

This wasn't necessary for me, but others may have had to use it for reasons
I don't know.

Really?  Since 8.0?  I only noticed this starting with the latest RH9 kernel
update a few days ago.  At any rate, I'm personally glad to see this
FreeBSD-ish behavior I came to know and love.
