Goto your /etc/yum.repos.d and edit CentOS-Base.repo and do the following;

under [base] add
exclude=firefox

Under [centosplus] add
includepkgs=firefox

Very good info...although at my company we manage our AIX and Linux servers
with advocent/kvm when ssh is not an option.  At home, this may come in
handy!  Thanks!

RE: Re: /etc/inittab: Serial access/ Console Server

yeah, when I asked this yesterday I had no idea the depth of response
would be so informative.

comparative analysis of kvm's and console servers shows that both have
*very* different applications, perhaps not comparable in the end.

we run 70+ nodes, alot of centos boxen, and lots of routers, switches,
load balancers and firewalls added to the mix.  lots o' remote console
access is required cause the colo is in silicon valley.  so serial line's
I doubt are going away, hehe.

Thanks to Rodrigo yesterday, he responded within 5 minutes to my question,
which got the lab config done. : )

Then today at the colo to see the in-depth info by pctech member, I was
able to connect up another wave of machines and get out of silicon valley
in time to see some world cup!

Did try again with a larger initial partition on the hard disk and was
able to "yum groupinstall" both GNOME and KDE, then clean up and fit it
all on the USB stick as described earlier - used 1.7GB with my setup.

Please report how it goes.

But - this will effectively exclude all other centosplus packages.
May/may-not be what was wanted.  I've also played with protectbase and
found it difficult to find the right combination of protect=0/1 and
include/exclude to get the desired behavior to allow some packages from
add-on repos.  Eventually ended up with protect=1 for all the repos I
wanted to use which kind of defeats the purpose.

PXE Boot Live CD

Is it possible to boot the Live CD through PXE? I've tried using Red Hat's PXE 
setup tool but have been unsuccessful.

I was afraid this was the answer.  The trouble here is that, come 4.4,
the firefox package in the base is going to be newer than the one in
centosplus.  I don't want to exclude firefox from the base, I want the
most recent one from either of the base or plus repos, without having
to get everything else from the plus repo.

This exclude is what I've used for now, but I think it's sub-optimal.

> Under [centosplus] add

This doesn't appear to be necessary in combination with the exclude
and protect=1 on base.  Hmm, what would happen if I left out the
exclude for base but used the include for plus?

When you use protectbase ... you are saying this:

I tried this with the kernel* packages and it doesn't do what I hoped,
unless I also turn off protect on base, which sort of defeats the
purpose.  Oh, well.

Related question:  How does one get a list of the contents of a repo
so as to maintain a correct includepkgs line, while still having the
includepkgs line present?  E.g. suppose some new package is added to
centosplus that I might want to use to update a base package.  If I
have an includepkgs line for centosplus, "yum check-update" will never
show me that a new package is there, because it will ignore everything
except what's already in the includepkgs line.

How I do it is with a separate config file (not named .repo) that you
can pass in via the command line ...

yum -c /path/to/yum.check.conf
