As far as I can tell, its two proposed solutions are:
1. Use short lease times ("Firstly")
2. Boot using IPv4 instead ("Secondly")
The second is not 'PXEboot working with DHCP+IPv6' - I'd have thought
the obvious answer would be to use IPv6+stateless configuration if
solutions avoiding using DHCPv6 are to be permitted!
(1) does not help much if one is trying to work out what to serve
to the server concerned based on IP address (which is normally the
only thing you have).
