We can certainly change this. The flavor of klogd comes from the fact
that it was written for a production environment. We use the message
forwarding capability of syslogd to concentrate all messages on one
machine. Our users wouldn't have a clue what any routine kernel
messages were about.
I do understand how this could be a problem in a single-user or new
user type environment. To that end I will change the default value on
our production sources of klogd.

Before I release the new version of sysklogd we should perhaps come to
a consensus on this issue. If we put a new binary with different
behavior we will probably get flooded with inquires as to why there
are messages like "VFS: disk change..." suddenly being produced.
So my question to the group is how to change this behavior in a
coherent fashion. Perhaps we need to make changes to the kernel
source now, prior to the release of the new sources.

I got fooled because I only looked at a head -25 listing of the
relevant source file as I was preparing the mail message. My mistake.
