Originally derived from Red Hat Enterprise Linux (RHEL), Oracle Linux (OL) contains minor differences, such as those necessary to differentiate itself e.g. modified /etc/redhat-release and /etc/issue file content, as well as /etc/enterprise-release, /etc/system-release, /etc/oracle-release files, etc.
Latest Oracle Linux versions additionally provide an alternative, compatible kernel - the Unbreakable Enterprise Kernel (UEK) along side the native Red Hat compatible kernel (RHCK).
Following is a list of RHEL major release/update kernel versions/release string content along with corresponding OL information.
