[syslog-ng] klogd back for syslog-ng-2.x ?

Guys I haven't touched syslog-ng since I last installed 1.6 2 years ago on RHEL4. I'm trying to upgrade to 2.x and I noticed that the init script for RH you provided in the contrib dir actually starts up syslon-ng and klogd. I thought syslog-ng was a total replacement for syslog including klodg ? I checked the older script I have for version 1.6 and sure enough it doesn't start klogd. I'm confused now as to whether I've been running this the wrong way or if you simply rewrote syslog-ng to rely on klogd again. Can anyone elaborate ? thx -- stucky
