Correct, by rules like this:
KERNEL=="vd*[0-9]", ATTRS{serial}=="?*", ENV{ID_SERIAL}="$attr{serial}",
SYMLINK+="disk/by-id/virtio-$env{ID_SERIAL}-part%n"
However I don't know if that convention is necessarily a good one to
follow (it's completely different from the one we use in other parts
of the API for example).
