Re: json.cfg - would it make sense to put it as kernel argument

[Andrew Stuart]

It’s also worth considering at some later stage being able to load the json.cfg 
from a url as shown below.

But not now, all I would really be happy with at the moment is a way to 
directly inject the config via the kernel boot arguments.

set timeout=0
menuentry "rumpkernel" {
        multiboot /boot/simple_hw_generic.xen ROOTFSCFG=/json.cfg
}

i.e:

set timeout=0
menuentry "rumpkernel" {
        multiboot /boot/simple_hw_generic.xen 
ROOTFSCFG=http://www.example.org/config/json.cfg
}
