When upgrading from RH 6.0 to RH 6.1... The next thing I noticed was that my "/etc/httpd/conf/httpd.conf" file no longer had the <VirtualHost ...> information in it. To fix this copy the missing <VirtualHost...> information from the httpd.conf.rpmsave file created by the upgrade. Then issue the following command: /etc/rc.d/init.d/httpd reload
I have marked the httpd.conf %config(noreplace) for an upcoming errata release.
