Yes, we can. I have thought CentoOS is not changing packages coming from
upstream. So, we need to patch
/usr/lib/python2.3/site-packages/yum/transactioninfo.py, see
http://devel.linux.duke.edu/cgi-bin/viewcvs.cgi/yum/yum/transactioninfo.py?revision=1.33&view=markup.
Look at remove method. I'm sending patched file.

Yes, I have. We should go different way. We will use exclude_hook
finally, but not now.

To sum it up. The code I'm sending, is really pre-alfa. Because I have
tested it on machines where yum is updated, code work with iftop, which
has been updated by Dag a few days before. You can change in
yumfirst.py: yumname = 'iftop'

Plugin works pretty fine:
yum update
yum install expect iftop
Both command are run and only iftop is installed/updated.

The plugin should be extended to work event in those cases:
yum install expect
yum update expect
And here comes exclude_hook.

So, give it a try and if it's ok, I'm gonna extend the functionality.
