s/id/is/

This really entangles the meta-virt dynamic layer with the xilinx
layers. You need to have an understanding of one, to really understand
the other.

If we are setting or appending to a variable, it really should be
defined in meta-virtualization.

Is there a way to move the functions that are using this variable
into the main Xen meta-virt recipes, in such a way that this is
a generic way to customize the boot ?
