commit 0331c27f115b6e9ba51508d7dbba13f41c290d54

    Make first ucf use more silent
    
    When we upgrade from non-ucf packages version, old configs differ from new and
    ucf ask a question to user even if old configs was not changed from dist.
    
    Check if old configs was not change and silently replace them with new version
