Hostname will continue to return localhost.localdomain since, at the
time the hostname command was used in /etc/rc.d/rc.sysinit, that's
what's in the /etc/sysconfig/network file on DHCP clients.

You'd need to change the dhclient script to extract the given host name
from the leases file and do a "hostname extracted-data" to change it.
