Hi,
I did an centos update from 7.4 to 7.5 and the krb5 package altered the existing and used config file! That should be a no go from my pov, as in my setup it broke some services which had a problem with the includedir line which was added.
Shouldn*t there be a rpmnew config file be created instead with the new/optional/added settings?
