Its named FOG because it is a “free, open-source (Norton) Ghost.” It uses iPXE to netboot a minimal Linux environment that can clone or restore a hard disk image. It includes a web UI for managing machines and disk images, among other things. There is also a client you can install on machines to remotely administer them.
It is very similar to DRBL/Clonezilla but for a slightly different purpose.
You aren’t wrong, but this is a shitpost.
