We are using this in our %post section for RHEL3:

--- 8< ---
########################################################################
# Set hostname, needed by cfengine
if [ -f /etc/sysconfig/network ]
then
    . /etc/sysconfig/network
fi
if [ -z "$HOSTNAME" -o "$HOSTNAME" = "(none)" ]
then
    echo "*** No host, can't install ***"
    exit 1
fi
/bin/hostname $HOSTNAME
--- 8< ---

Remember, %post commands are run chrooted to the newly installed system.
