On RHEL and CentOS 7 host name is kept in /etc/hostname, so even if SET_HOSTNAME has a value, the machine was keeping localhost.localdomain as name. This way the hostname file gets overwritten with contextualization variable value. I'm supposing that file /etc/hostname will be existing in next releases too (OS_VERSION >= 7)
