I just change the restart command on the named service. Instead of
letting puppet do a:
/sbin/service named stop and then start
I have it do
/sbin/service named reload.
Which on redhat only runs
/usr/sbin/rndc reload
If that fails, named keeps running with the previous config it loaded
with no interruption, puppet complains that the restart failed, I get
notified and fix the zone file.
