After system packages are updated with "yum update", config files which could not be overwritten are not replaced, but we can find *.rpmnew files near by. By design system administrator must merge config files.
In Gentoo Linux there is a etc-update tool, which allow to merge config file changes interactively, like that:
Beginning of differences between /etc/pear.conf and /etc/._cfg0000_pear.conf [...] End of differences between /etc/pear.conf and /etc/._cfg0000_pear.conf 1) Replace original with update 2) Delete update, keeping original as is 3) Interactively merge original with update 4) Show differences again
I wonder if there is a way to merge configs interactively in RHEL/Fedora/CentOS?
