non-interactive update in Debian is broken

The server team complains about a warning that breaks non-interactive auto-update process in deb-based distros.
Running minor or major upgrade one gets a warning from deb packaging about Columnstore.xml was changed since installation. The important fact is that nobody changes the xml. The xml file attributes are changed by a number of clauses in columnstore-post-install:

• mcsSetConfig in columnstore-post-install
• mcsSetConfig in columnstoreSyslogSetup.sh
• chown in columnstore-post-install

The suggested solution is to remove offending mcsSetConfig clauses and move chown into corresponding post-inst step scripts of a packaging systems(for both RPM and DEB).
