Hmm... I don't follow. Why wouldn't it be able to? All the
informations are in the log. It is messy but it's there. If you want
more structured information, u{dev|disks} already maintain device
libarary - what maps to what, connected how with what attributes and
so on. Sending them off to the log machine as device hotplug events
occur and consulting it when post-processing log message would work
fine. All you need is just some python scripting. I don't really see
much point in messing with device names directly. The only thing is
that the raw log would be prettier. I don't think that is useful
enough to justify changing kernel device names.

Thanks.
