There is no support for DHCPv6 Reconfigure extensions, and this option is documented informationally only. Do you have any idea what it is and how it got into the leases file ?

The file grows and gets shorter all the time. So I do guess now that isc dhclient is NOT compatible with itself. Yes, I had to patch dhcp to make it work with ppp as isc does not give ppp a well deserved place. see https://bugzilla.redhat.com/show_bug.cgi?id=626514. ppp plus pd is the way to go for ipv6 I read.
