Apache updates reset group permissions
 

I am helping in the administration of a server running RH Enterprise Linux 3 Update 3. This machine is a webserver as well as file server for a research group on the university campus I attend. The webserver it is using is Apache 2.0.46.

We have noticed that whenever an update is pushed to RHN and installed on our machine, the permissions are reset so that group members are unable to write to the /var/www/html directory.

eg,

drwxr-xr-x

What we want is

drwxrwxr-x

which is trivial to fix, just use chmod. However, we were hoping there would be a way to automate the process by use of a local script called at the end of the RHN update routine. Is this possible? What config files do I need to edit to do this?
