I think the "raw" string is known to libvirts libxl driver. It could do
a strncmp() and fill also ->script. Then libxl would call that thing by
itself, libvirt does not need to know about such internals. Of course
that would mean an additional "script=$path" is still not supported  by
libvirt. But thats not a loss because whoever is relying on can just
copy its own file into XEN_SCRIPT_DIR. After all only our own dmmd thing
requires a script because that is its whole purpose (carry the block
configuration along with the vm configuration).
