Since Kier has said that each bug-fix series 3.1.x and 3.2.x maintain
hypervisor <->  ABI compatability, I reckon we should name the hypervisor
according to this version, so  '/boot/xen-3.1.gz' and '/boot/xen-3.2.gz'.
That way people can update the minor releases 3.2.0, 3.2.1, 3.2.2, etc
and not have to worry about changing grub configs.

Personally I'd like to see upstream get serious about Hypervisor <-> Tools
ABI compatability. If you look at the changes in ABI from 3.1 to 3.2 trees
it would have been pretty trivial to maintain compatability for new 3.2 
hypervisor against old 3.1 tools. This is an idea that's been rejected
many times before, but I'd still like to see it. cf new Linux releases 
don't break glibc each time. Then we could finally get out of the lock-step 
upgrades..

Dan.
