That sys log is working.  That is normal debug output from the -d
The -n in klogd stops it releasing the terminal.  You will be able
to see messages being appended to /var/log/sys.log

Suggest you install this version then try and make it fail.

Both can be run from /usr/sbin. You can do
/etc/rc.d/rc3.d/S10sysklogd  stop
and/etc/rc.d/rc3.d/S10sysklogd  start

If this fails you can check the flags -d and -n in the man pages
of klogd and syslogd.  Just repeat the stop, then run it under debug.

Try
gdb  /usr/sbin/klogd
run  -d          or just plain run
and try and make it fail
