Hi, I was reading a post here (if interested): https://forums.opensuse.org/t/do-i-have-to-babysit-updates-and-other-questio... I decided to then pass rpmconfigcheck in Konsole. Thinkcentre-M57p:~ # rpmconfigcheck Searching for unresolved configuration files Please check the following files (see /var/adm/rpmconfigcheck): /etc/chrony.conf.rpmnew /etc/postfix/main.cf.rpmnew /etc/postfix/master.cf.rpmnew Thinkcentre-M57p:~ # cat /var/adm/rpmconfigcheck /etc/chrony.conf.rpmnew /etc/postfix/main.cf.rpmnew /etc/postfix/master.cf.rpmnew Thinkcentre-M57p:~ # In the post link above, one speaks of using 'diff' but it is unclear of how to use this to compare .rpm packages. How should I think of these .rpmnew packages I see listed above?
