yum erases my syslog-ng; how to stop it?

[GlueGuy]

Three times now my syslog-ng has gotten erased by a yum update. This is on a year-or-so old Cacti-EZ installation. I think what happens is that an update for syslog comes along, and for reasons I don't understand, yum decides to erase syslog-ng. The only clue I have is this (latest) entry in the yum.log:

Oct 07 06:02:57 Erased: syslog-ng

This may be old news, as this is the setup we currently have running:

Cacti Version - 0.8.7e
Plugin Architecture - 2.6
Poller Type - Cactid v
Server Info - Linux 2.6.9-89.0.28.plus.c4
Web Server - Apache/2.0.63 (CentOS)

We're in the process of replacing this older server with a newer one. So I'm just looking for a tip on how to stop this in the future on our new server (which is pretty much up to date on cacti and plugins).

Set exclude=… statements inside the yum configuration to ignore certain packages during a yum update.

That looks like that would work. Thanks phalek!
