Hey! Thanks for the topic!
If it does not exist
mkdir /var/www/fog/iso
Copy ISO file
cp SOURCE_PATH/ISO_FILE /var/www/fog/iso
Add
/var/www/fog/iso * (ro, sync, no_wdelay, insecure_locks, no_root_squash, insecure )
in
/etc/exports
Run
sudo service nfs-kernel-server restart
sudo service rpcbind restart
Add a new menu in FOG WEB GUI
initrd http://${fog-ip}/fog/iso/ISO_FILE.iso
chain memdisk iso raw
WORKED PERFECTLY!
