Yea, sure. "testing/debugging purposes". I don't mind if that breaks.
When developing stuff I do tricks which can break on
qemu/libvirt/whatever upgrade all the time for all kinds of reasons, for
example because libvirt doesn't support $new_hot_qemu_feature yet.
For production usage better don't do that and stick to the "opt/" prefix
recommendation. If adding something outside opt/ turns out to be useful
outside testing/debugging we should add a proper qemu cmd line option
for that instead of suggesting users to fiddle with -fw_cfg. No
question about that.
But I don't think we should break -fw_cfg usage as testing/debugging
tool by enforcing opt/ prefix.
cheers,
Gerd
