Here's my feedback on the installers:

RHEL 4.x (32 and 64) syslog-ng server installer: No problems. Replaced an older (2.0.4) version of syslog-ng without any issues.

SuSE 10SP1 - 32bit syslog-ng client installer: Installed correctly but didn’t replace the existing syslog-ng installation (1.6.8) which ships with SuSE 10SP1.

SuSE 10SP1 - 32bit syslog-ng server installer: Installed correctly, replaces the current syslog-ng implementation and moves the configuration to /opt/syslog-ng/etc/syslog-ng.conf. It didn't replace/remove the rcsyslog script. Must now use /opt/syslog-ng/sbin/syslog-ng to stop/start/restart the process.

Steve
