@Sebastian-Roth I kind of got pulled in a few different directions.

But the concept is to use grub to make an ipxe call. From grub we would use the menu that would look a bit like this

menuentry 'Quick Image' { set root='hd0,msdos1' linux16 /boot/ipxe.krn initrd16 /boot/qimage-initrd }

Then the qimage-initrd would contain something like

#ipxe param mac0 ${net0/mac} param arch ${arch} param username fog param password password param qihost 1 isset ${net1/mac} && param mac1 ${net1/mac} || goto bootme isset ${net2/mac} && param mac2 ${net2/mac} || goto bootme :bootme chain -ar http://<fog_server_ip>/fog/service/ipxe/boot.php##params

Understand this is still a concept, but all of the bits look like they fit together nicely. That should provide the quick image menu for unregistered hosts.

Update to thread: These sed scripts can/could be called from a fog postinit script to ‘patch’ the fog scripts on each FOS boot. This way you would never need to unpack the inits and would fully support updated scripts in the future.

I did write a tutorial on the postinit scripts here: https://forums.fogproject.org/topic/9463/fog-postinit-scripts-before-the-magic-begins
