@lebowski while its not dynamic data fog does install/alter files in
/var/www/html/fog
/etc/<apache_config>
You could (might want to) consolidate /images and move it into /opt/fog/images you can do that with a loop mount or when you install FOG point to that location instead of the default location of /images.
If you are going to use dnsmasq for your setup then /etc/dnsmasq.conf and /etc/dnsmasq.d
The other issue is installing/upgrading fog. If you use the github method you need a location to clone the repository.
