I have been using the isc-bind-esv repository on Centos 7 since it was

Today (happily on a cloned test server!) I repeated this with the upgrade
being from 9.11.6 to 9.11.6.P1-1.2.el7.
It seems that the package names have changed and that Bind is now installed
in a new directory structure below /opt/isc. In my case, a previously
working authoratitive configuration is now comprehensively broken.
Before troubleshooting, I was wondering whether I had missed any release
notes or similar which might explain what is going on.
Probably ISC's new packages have installed a "Software Collection" to avoid
conflicts with "native" packages. Read the scl(1) manual page for more
information. To get a shell with the proper context to manage named, you'll
need to run something like `scl enable isc-bind bash`. Or to run ad hoc
commands, `scl enable isc-bind -- named -V`, etc.. And as you noticed, named's
configuration and data are now under /opt/isc/isc-bind/.
If the old XPG4 and POSIX rules are to be at least paid some attention
then the config data should be under /etc/opt/isc/named and the software
binaries and libs stay in /opt/isc/named with logs going to the correct
/var/opt/isc/named. But those are old rules for ensuring separation from
the vendor OS. With systemctl and other new paradigms then all manner
of oddball stuff may happen.
