Hello Huw,

You would get this same output from rpm were you to install the rpm
manually.  I imagine yum is just taking stderr from rpmlib and giving it
back to you.  Yum probably has no way to know if it's a "real" error or
a simple warning like .rpmnew.  If you know you can disregard certain
errors, why not add some egrep logic to your wrapper?

GREP="egrep -v '.rpmnew|second bogus message|third bogus'"
/usr/bin/yum -y -d 0 -e 0 update yum | $GREP
/usr/bin/yum -y -d 0 -e 0 update | $GREP

Just my 2 cents.  I'll wait to hear from the masters  ;-)
