Thanks a lot for your help. I think I need to expend some time looking for the best solution here. I will update the thread with progress.

I have several custom iso images based in Ubuntu 12.04 that I need to install in embedded devices. The network cable is the only interface that I’ve got after the machines are boxed.

These iso images use a preseed file to create partitions and add settings but the installation is not completely automatised and some user interaction is needed to choose keyboard, language and a couple of other things.

I managed to add one of the isos to the PXE boot menu, but I got some problems:

• I don’t have access to a keyboard to navigate the menu and select the iso

• The iso didn’t use my preseed file

• The lack of a keyboard stopped me from choosing the installation options (can I use a kickstart file in addition to the existing preseed)

• The installation failed because Ubuntu was looking for the image mounted in /cdrom

• Even if I managed to do it this way, I would have to change the PXE default menu every time I wan’t to install a different iso (this wouldn’t be a big problem)

I was wondering if I’m taking the wrong approach here. It would be nicer for me if I could add the iso as an image and schedule an installation on the next boot. Maybe even have some commands to send to answer the questions asked during the installation.

I’m new to FOG and I would appreciate if you could point me in the right direction.
