True in principle, but in practice, you can't always run strace to
find out what's going on, either because the problem starts in early
boot or because the problem is triggered indirectly through daemons
etc.

I really much favor for distro's to make dmesg -n4 the default.  There
is no reason to bother average users with KERN_{NOTICE,INFO,DEBUG}
stuff unless they ask for it.
