I don't think it's a complicated approach we are talking of a system
log like syslog with a temporal information, nothing more.

Simply because I think that we should avoid to include in the kernel
things we can do in a simply way at user space level. I think this
patch is well done but it's one of the patches that are solutions "for
embedded only", but it's only my opinion.
