[syslog-ng] help on DNS issue when running syslog-ng chrooted

Hi, I'm a newbie to the syslog-ng. I just have the application installed and configured since yesterday and I like it already. However, I'm running into a problem. I hope someone on this list has done it already and can help me out. I'm running syslog-ng in chroot mode, followed the instructions in http://www.campin.net/syslog-ng/chroot-jail.html. I also enabled DNS lookup so I can show the Cisco routers in their friendly names instead of IPs. The DNS lookup works fine until I enabled chroot mode. I copied "nsswitch.conf" and "resolv.conf" files into $CHROOTDIR/etc as well, just in case. BTW, the host is RHEL4 and I set SELinux to "permissive". Will my configuration work? If so, what should I check? Thanks in advance for help.
