Currently I am using chain to point menu items to the pxe boot files residing on another server. I know that this isn’t what FOG is made for, but it’s working for me and that’s all I can ask for.
That is the beauty of FOG and open source software. FOG is flexible enough to support doing things that it was never designed to do. Case in point the articles related to pxe booting your fav OS installer. That’s not related to FOG, but can be done with a little skill.
