The comment is also broken in that it has a stale link to the old wiki. Noting here so it gets fixed.

> Automated rpm upgrades from the security:shibboleth repository replace /etc/httpd/conf.d/shib.conf, even though that file has been customized for the customer's application.
> The desired behavior is for the rpm to leave the current file intact, but this does not happen because there are new changes to the packaged shib.conf file each time an upgrade takes place, and those changes cause rpm to replace the file according to the rule explained here: http://www.rpm.org/max-rpm/ch-rpm-upgrade.html
> The changes to shib.conf for each upgrade are two alias lines for the logo image and css:
> --- shib.conf.R	2010-07-23 13:26:17.000000000 -0400
> +++ shib.conf	2010-12-14 17:09:19.000000000 -0500

> Those lines always contain the new version number, so rpm always sees this file as needing to replace the current config file, which breaks our customized config file each time we upgrade.
