Unsure which document this should go in:

This section aims to document special considerations for using packages in Image Mode.

The nginx package

By default, the documentation root configured for the `nginx` daemon is `/usr/share/nginx/html/` which is not writable in RHEL Image Mode. When building Image Mode containers based on nginx, an alternative document root can be configured by placing a drop-in configuration file in the `/etc/nginx/default.d/`.
