Well, I think people who use ftrace are m,ore likely to look at kernel
messages than most...

So what would be more interesting is if there's some distro support
for showing kernel notifications..

I see new notifications for calendar events, for devices that got
mounted, for a lot of things - so I'm really wondering if somebody
already perhaps had something for specially formatted kernel
messages..
