I am well able to read manpages, thank you. Occasionally, I even do
so.

Today, I play a little bit with the SuSE box.
It looks like klogd on startup reads everything that is already in the
kernel ring buffer and dumps it off to syslog before going to its
normal operation mode. This is not mentioned in the man page but is a
Good Thing IMO. It could be possible that klogd doesn't care about
messages that are already there when it comes up. But klogd is smart
and does what I feel appropriate.
SuSE prevents this from happening by using klogd -o to dump the
information into a separate file. This is a Stupid Thing IMO.
Case closed ;-)
