Not unless you reboot the system, which I thought was a good thing to do (to
ensure my runtime was completely up-to-date). If rebooting at that point is a
source of trouble, I think we could document this in release notes.
But then again, it makes no sense to postpone kernel upgrade after userland if
we can't reboot anyway. Maybe this means we have to change order ?

But the etch linux-image-* package directly depends on udev, so that's not

Nothing, it is more like: if hotplug is NOT installed, then we definitely want
g-v-m functionality. Otherwise we don't want it because it'd be at the cost of

Not necessarily. Later in the install process, when we install etch linux-image
which drags in udev, removal of hotplug will be forced. Then the dependency on
"gnome-volume-manager | hotplug" is no longer satisfied, and apt has to figure
out that installing gnome-volume-manager does the trick (I'm not sure if it is
able to figure that out, though).
