effectively your boot menu likely needs to be:
params param mac0 ${net0/mac} param arch ${arch} param qihost 1 kernel bzImage loglevel=4 initrd=init.xz root=/dev/ram0 rw ramdisk_size=127000 web=http://${fog-ip}/fog/ consoleblank=0 rootfstype=ext4 mac= ftp=<storageIPHere> storage=<storageIPHere>:/images/ storageip=<storageIPHere> irqpoll chkdsk=0 capone=1 type=down img=<imageNameHere> imgType=n imgPartitionType=all imgid=2 osid=<imageOSIDHere> imgFormat=<imageFormatHere> imgfetch init.xz bootReplacing as appropriate:
<storageIPHere>
<imageNameHere>
<imageOSIDHere>
<imageFormatHere>
with your relevant information.
Ultimately finding these pieces of data relevant to your specific image will be the hardest part, but once done I believe this will do what you are wanting/hoping.
