I tend to create my own directory heirarchies when I set up new websites. 

I recently switched to the Fedora Core 12 desktop linux distribution for my development environment. When attempting to install formVista using the setup program I wrote, I kept running into weird permission denied errors. 

It turned out to be an SELinux policy violation. I had not set the required SELinux "type" on my custom "html" directory.

Instead of just disabling SELinux, I did some searching around and determined I needed to add the "httpd_sys_content_t" type to my directory.

chcon -Rt httpd_sys_content_t html

which basically says add the "http_sys_content_t" type to everything in the html directory.

There's a nice SELinux administration tool available for Fedora Core 12 which lists out all the various settings available and it was intrumental in helping me find the correct setting. It's called system-config-selinux and is part of the policycoreutils-gui package.
