alexs writes "Red Hat's response to update bind through RHN, patching the DNS hole, made a fatal error which will revert all name servers to caching only servers. This meant that anyone running their own DNS service promptly lost all of their DNS records for which they were acting as primary or secondary name servers. Expect quite a few services provided by servers running RHEL to, errr, die until their system administrators can restore their named.conf. Instead of installing etc/named.conf to etc/named.rpmnew, Red Hat moved the current etc/named.conf to etc/named.conf.rpmsave and replaced etc/named.conf with the default caching only configuration. The fix is easy enough, but this is a schoolboy error which I am surprised Red Hat made. Unfortunately we were hit and our servers went down overnight while RHN dropped its bomb and I am frankly surprised there has not been more of an uproar about this."
