Indeed.

Ok, I've modified my 1.5 kernel to use a "long long" as the hostid. It's a
sparc, and it still gets set to the ssame host id value as it did when it
was just a long, proving that it's backwards compatible :-)

I think that having two interfaces on the same Ethernet broadcast domain
is sufficiently rare to be worth hand-configuring the interfaces for! The
machine would have to be a router from an IPv6 config viewpoint anyway!

Therefore, since nobody has yet said it would be a bad idea, I'll start
munging ifconfig and rtsold to use this 64 bit value...

Patches will be submitted in due course :-)
