// For some distros, we don't want to use the full version from VERSION_ID. One example is
// Red Hat Enterprise Linux, which includes a minor version in their VERSION_ID but minor
// versions are backwards compatable.
//
// In this case, we'll normalized RIDs like 'rhel.7.2' and 'rhel.7.3' to a generic
// 'rhel.7'. This brings RHEL in line with other distros like CentOS or Debian which
// don't put minor version numbers in their VERSION_ID fields because all minor versions
// are backwards compatible.
