After a yum update I receive this worning :
warning: /etc/fail2ban/jail.conf created as /etc/fail2ban/jail.conf.rpmnew
Those warnings are expected if you have made changes to your configuration files. yum is kind enough to not overwrite your existing modified configuration, but instead writes the new default configuration file to a .rpmnew file, which you can then review and perhaps incorporate the new defaults etc to your own configuration. This is OK. The kernel module warnings are also of no concern.
