I've just realized a couple of things:
(1) Reason why postinst removal of base.img doesn't work: Because it
was the libguestfs-tools postinst (not libguestfs0). In any case this
is not so important, since the new supermin appliance is located in a
different directory now because of multiarch.
(2) The attached patch gets rid of some appliance installation rules
that aren't really needed any longer.
