The problem isn’t related to the program itself as far as I can tell. It’s called “facet” though, it’s made by the Dutch government. No version is mentioned in it. The Client runs some Linux. (the Facet server runs Centos 6.5 so it’s possible the client uses files from that) It’s stored as vmlinuz0 and initrd0.img. (It also comes with pxelinux files but those aren’t used in the working fog config, ie pxe advanced menu)
Our Fog server (1.2.0) runs on Debian 4.6.3-14.
I figured that if I could break memtest I’d have a clue as to why I can’t load another kernel.
I’ve added just this menu to the taskTypes tables. Basically a copy of the memtest entry. The advanced boot menu is full of various boot images, this is unrelated to the host manager though.
