nodeset through the ipxe plugin writes the BIOS, UEFI, elilo and
pxelinux files of a node under xcat/ipxe/nodes, and the scripts name
that directory. An xnba node still gets xcat/xnba/nodes. SvrUtils reads
the nodeset state of both. An x86_64 osimage accepts netboot=ipxe, and
the noderes.netboot description lists it.
