Linux: default fonts

Hi, I did an upgrade today on CentOS 6.3 to 6.9 and the user complained that their default font changed to “Preformatted text / liberation mono”. Can anyone tell me what file to preserve on the next update so that doesn’t change? thanks!!

Preformatted text is a style name, not a font name. The font name is next to it, Liberation Mono. It looks like that user opens a plain-text file. Instead, he should use ODT. In order to keep particular fonts as defaults (for particular styles), he should better create templates and set a template as the default template as necessary. In such a case the settings will survive any update (of course, if the user profile is not corrupted).
