Thanks for the reminder, and sorry for very very late answer. PFA
rebased patch on current head.

I unfortunately didn't have time yet to read carefully the newly added
infrastructure (30833ba154e0c1106d61e3270242dc5999a3e4f3 and
following), so this patch is still using its own copy of partitions
list. I hope I can work on it shortly, but I prefer to send the
rebased version now, since it's still a POC with knowns problems and
questions, and I'll more than welcome any guidance with it.
