isc-bind-esv Repository - "yum update" doing undesirable things!

First of all, thanks for trying these packages out and apologies for the
trouble caused.  This is an intentional change in a repository which ISC
has always been describing as experimental [1].

A few months ago, we decided that Software Collections [2] are the
preferred long-term solution for our RPM packages.  Among other things,
this was prompted by the package conflicts people were running into when
using our Coprs [3].  What you observed on your server is an update from
non-SCL packages to SCL packages.

To make your previous setup work with SCL packages, please move your
/etc/named.conf to /opt/isc/isc-bind/root/etc/named.conf.  If you
previously enabled named startup upon boot and you still want that to be
the case, please run:

    systemctl start isc-bind-named

BIND utilities (e.g. dig, rndc) are available after enabling the
Software Collection, for example using:

    scl enable isc-bind bash

This disruption was a one-off - we plan to soon move our Copr
repositories away from their current experimental status.  Once that
happens, care will be taken not to break existing installations.

Once again, apologies for the inconvenience.  If you have any further
questions, please feel free to ask them.

Hope this helps,
