Public bug reported:
When using "inet6 dhcp" in /etc/network/interfaces, ifup always sets
sysctl net.ipv6.conf.%iface/.//%.accept_ra=0
This seems to assume that DHCP will always be able to provide a default
route, which is not always true (This was forbidden in the DHCPv6 RFC)
or desirable (The IPv6 routers sending RAs might have more up to date
information about their own availability than the DHCPv6 server.
There should be an option which uses stateful DHCP to get an IPv6
address, but which still uses RA to find routers. I think that it's
most intuitive that this be called "DHCP" and leave "auto" for the
stateless variety. If accept_ra needed to be turned off, I think that
this would better be done by dhclient, since that daemon would know if
it received and installed a default route.
