Description Ryan O'Hara 2008-12-21 17:58:22 UTC 
If IPV6INIT is set to "no" in an interface's ifcfg file, dhcp6c will still get called. This seems incorrect. IPV6INIT = "no" should disable IPv6 for that interface and the ifup-eth script should honor that.

Here is the relevant code form ifup-eth:

# IPv6 initialisation?
/etc/sysconfig/network-scripts/ifup-ipv6 ${CONFIG}
if [[ "${DHCPV6C}"  = [Yy1]* ]] && [ -x /sbin/dhcp6c ]; then
    /sbin/dhcp6c ${DEVICE};


The ifup-ipv6 script actually checks the value of IPV6INIT, and if it is not set to "yes", the script exits. Regardless of what ifup-ipv6 does, ifup-eth will continue to run dhcp6c.

Bottom line that that I would expect IPV6INIT="no" to prevent dhcp6c from being run.

You have conflicting configuration - you've explicitly configured dhcp6c to run.
