This looks way better than previous version. Thank you for working in my
suggestions. There are still some small problems, but I'll fix them
before merging.
Also, I'm moving some hunks between some patches AND I'm reordering some
patches too. For instance, patch 02/13 introduces a temporary regression
as it requires aliases to be assigned to disks, but that doesn't happen
until patch 09/13. If these are reordered then no regression occurs.
Anyway, good job! What should be done in a follow up series is to emit
events on device attach/detach. Management apps will certainly value that.
